Adda Quinn is best known as the first wife of Larry Ellison, the businessman who later became famous as the co-founder of Oracle Corporation. Unlike Ellison, whose career, wealth, and personal life have received decades of media attention, Adda Quinn has remained a very private person. Her name appears mainly in biographies about Ellison because she was part of his life long before Oracle became a global technology company and before he became one of the world’s wealthiest business figures.
That early connection has made people curious about who Adda Quinn is, how she met Larry Ellison, what happened to their marriage, what she did for a living, and where she is today. Public information about Quinn is limited, so many personal details should be discussed carefully. What is more clearly documented is that she married Ellison in 1967, their marriage ended in 1974, and she later developed a life away from his growing public fame.

Who Is Adda Quinn?
Adda Quinn is a private American woman mainly known because of her past marriage to Larry Ellison. She became part of his personal story before he created the business career that would eventually make his name closely connected with Oracle, Silicon Valley, database software, and enormous wealth.
Quinn is very different from many people connected to famous billionaires. She has not built a public brand around her former marriage, does not appear regularly in interviews, and has not become known as a celebrity personality. Most of the interest surrounding her comes from people researching Larry Ellison’s early life and marriage history.
Her importance in Ellison’s biography comes from timing. Adda Quinn knew him before Oracle existed. Their marriage covered a period when Ellison was still building his career and had not yet reached the level of success that would later make his lifestyle and business decisions international news.
Because Quinn remained private, many questions about her age, childhood, education, family, second marriage, and current residence are harder to answer with confidence.
Adda Quinn’s Early Life and Background
Very little reliable information is available about Adda Quinn’s early life. Her exact date of birth, childhood details, parents, and educational history have not been consistently documented by major public sources.
Some biography websites provide specific ages or estimated birth years, but those details are often repeated without clear evidence. For that reason, it is better not to treat an exact birth date as confirmed unless stronger documentation becomes available.
What is better known about Quinn’s life begins around the period when she met Larry Ellison in California.
This lack of early-life information is not unusual. Quinn was not a famous actress, politician, entrepreneur, or public figure when she was young. She became a subject of public curiosity mainly because the man she married later became one of the most recognizable names in the technology industry.
Her private background also helps explain why modern articles sometimes disagree about basic facts. There simply is not the same level of historical documentation available for her that exists for Larry Ellison.
How Adda Quinn Met Larry Ellison
One of the most frequently reported details about Adda Quinn and Larry Ellison is that they met through an employment agency in Berkeley, California.
At the time, Ellison was far from the billionaire lifestyle associated with him today. He was still working to establish himself professionally and had experience in programming and technology-related jobs.
Their relationship developed during this early stage of his career, and the couple married in 1967.
This is an important part of Adda Quinn’s story because she knew Ellison before Oracle Corporation, before major business success, and before the intense public interest surrounding his wealth and lifestyle.
People searching for “Larry Ellison before Oracle” often come across Adda Quinn because their marriage belongs to that early period.
She was present during a time when Ellison’s future was still uncertain and when his career looked very different from the technology empire he later helped build.
The Marriage of Adda Quinn and Larry Ellison
Larry Ellison and Adda Quinn married in 1967. Their marriage lasted approximately seven years and ended in 1974.
Accounts of their early married life describe circumstances that were much more modest than the luxury later associated with Ellison. The couple reportedly lived in a small apartment during part of their relationship before later purchasing a home in Oakland, California, around 1970.
Ellison was still developing his professional path during these years. He had not founded Oracle, had not become a billionaire, and was not yet a major public figure.
This makes the marriage particularly interesting to people studying his biography.
Adda Quinn did not marry an already famous technology tycoon. Instead, she married Ellison while he was still trying to establish himself.
Their relationship therefore belongs to a period of career uncertainty, ordinary financial pressures, and changing personal ambitions.
Adda Quinn and Larry Ellison Marriage Timeline
| Year | Event |
| 1967 | Adda Quinn and Larry Ellison married |
| 1970 | They reportedly purchased a home in Oakland |
| 1974 | Their marriage ended in divorce |
| 1977 | Ellison later co-founded the company that became Oracle |
The dates make one thing clear: Adda Quinn and Larry Ellison had already divorced before Oracle was founded.
Why Did Adda Quinn and Larry Ellison Divorce?
The marriage between Adda Quinn and Larry Ellison ended in 1974, but the exact private reasons for their divorce are not fully documented.
Some online biographies connect the separation with financial problems, career pressure, different priorities, and Ellison’s ambitions. Those explanations may reflect parts of their situation, but detailed claims about private conversations should be treated carefully.
It is easy for modern celebrity articles to turn speculation into supposed fact when discussing relationships that ended decades ago.
What can be said more safely is that their marriage lasted about seven years and took place during a period when Ellison was still finding his direction professionally.
His later business success should not be projected backward onto the marriage. At the time of their divorce, he had not yet created the company that would eventually become Oracle.
The relationship remains an important part of his early personal history, but Adda Quinn herself has not built a public identity around discussing the divorce.
Adda Quinn’s Life Before Oracle
One of the biggest reasons Adda Quinn continues to attract online attention is her connection to Larry Ellison before Oracle.
Today, Ellison is associated with technology, enterprise software, databases, Silicon Valley, luxury properties, and billionaire rankings. None of that fully defined his life when he was married to Quinn.
Oracle’s origins came later.
In 1977, several years after Adda Quinn and Larry Ellison had divorced, Ellison helped establish the company that eventually developed into Oracle.
Because of that timeline, Quinn should not be described as an Oracle co-founder or as someone who helped build the company unless reliable evidence supports such a claim.
Her connection is historical rather than corporate.
She knew Ellison before the business success, before the global recognition, and before the lifestyle that later made him a major public figure.
That makes her part of an earlier and less glamorous chapter of his life.
Adda Quinn’s Career and Professional Life
While Adda Quinn is usually introduced as Larry Ellison’s first wife, reports about her later professional life suggest that she developed an independent career.
Multiple secondary profiles connect Quinn with the Electric Power Research Institute, better known as EPRI.
EPRI is associated with research involving electricity, energy systems, environmental questions, and technical issues connected to the power industry.
Quinn has been described in published profiles as working in areas related to business management, project management, research coordination, and environmental research programs.
This would make her role different from that of a laboratory scientist. A project or research manager may help organize teams, manage schedules, coordinate technical work, support budgets, and keep large research projects moving efficiently.
Her reported connection with Palo Alto and Northern California also fits the wider research and technology environment in which EPRI operated.
However, exact claims about her job titles, salary, department, or years of employment should be treated carefully when original employment documentation is not available.
The broader picture is more useful: Quinn appears to have developed a professional identity separate from Larry Ellison’s later technology career.
Adda Quinn and Environmental Research
A number of profiles link Adda Quinn’s career with environmental research and research management.
EPRI-related environmental work has covered subjects such as soil contamination, water quality, land use, industrial pollution, environmental risk assessment, PCBs, and the environmental effects of energy production.
It would be inaccurate to assume that Quinn personally conducted scientific research in every one of these areas. Her reported background is more closely connected with management and coordination.
Still, this professional direction makes her story more interesting than a simple celebrity-spouse biography.
While Larry Ellison became associated with software and databases, Quinn’s reported work was connected to research programs and environmental issues.
The two appear to have followed completely different professional paths.
That independence is an important part of understanding Adda Quinn beyond her marriage.
Adda Quinn’s Life After Divorce
After her divorce from Larry Ellison in 1974, Adda Quinn largely moved away from public attention.
People often search “what happened to Adda Quinn?” because Ellison became much more famous in the years after their relationship ended.
However, Quinn does not appear to have used the marriage to create a public career. She did not become known for television appearances, celebrity interviews, public memoirs, or regular comments about her former husband.
Instead, available information suggests that she focused on her own work and personal life.
This makes her different from some former spouses of famous people who remain part of celebrity culture long after a relationship ends.
For Adda Quinn, the opposite seems to be true.
As Ellison’s public profile became bigger, her own public presence became smaller.
Did Adda Quinn Remarry?
Several modern biography sources report that Adda Quinn later married George Sublett.
The name appears often enough in online profiles that it has become a common part of articles about her later life. However, detailed public information about the relationship is limited.
There is not the same level of widely available documentation around this reported second marriage as there is around her marriage to Larry Ellison.
For this reason, it is better to describe George Sublett as Quinn’s reported second husband rather than build a detailed personal history from unsupported information.
Dates, family details, and the exact course of the relationship should not be presented as certain without stronger evidence.
This is another example of why Adda Quinn’s biography needs careful wording.
Did Adda Quinn and Larry Ellison Have Children?
There are no publicly documented children from Adda Quinn and Larry Ellison’s marriage.
This question often appears because Larry Ellison later became a father.
His children David Ellison and Megan Ellison are well known because both developed successful careers in the entertainment industry.
However, Adda Quinn is not their mother.
They belong to a later part of Larry Ellison’s family history.
This distinction is important because readers sometimes connect every member of a famous person’s family without paying attention to marriage dates and relationships.
Adda Quinn’s marriage to Ellison ended in 1974, long before the later family chapter involving his children.
Adda Quinn’s Connection to Larry Ellison
Adda Quinn’s strongest public connection remains her former husband, Larry Ellison.
Ellison later became internationally known through Oracle and the technology industry. His career transformed him from a programmer and technology worker into one of Silicon Valley’s most influential business figures.
Because of his fame, people naturally became interested in his early life, marriages, former wives, children, and relationships.
Adda Quinn appears at the beginning of that story.
She was his first wife, and she knew him during a period when success was far from guaranteed.
That makes their relationship historically interesting even though Quinn herself has stayed away from media attention.
Her connection to Ellison explains why people continue searching for her name decades after their divorce.
Where Adda Quinn Fits in Larry Ellison’s Marriage History
Adda Quinn was the first wife of Larry Ellison.
After their marriage ended, Ellison later married other women, including Nancy Wheeler Jenkins, Barbara Boothe, and Melanie Craft.
His marriage history has attracted attention because of his fame and wealth, but Quinn occupies a unique position in that timeline.
She was there before Oracle.
She was married to Ellison before his public image became connected to Silicon Valley success.
This also helps clear up confusion about Larry Ellison’s children. Barbara Boothe, not Adda Quinn, is associated with the part of his family history involving David Ellison and Megan Ellison.
Understanding the timeline makes Adda Quinn’s role much clearer.
How Old Is Adda Quinn?
The exact age of Adda Quinn is not reliably confirmed in major public sources.
Some websites publish estimated birth years, but those figures are not always supported by strong documentation.
Because Adda Quinn married Larry Ellison in 1967, writers sometimes attempt to calculate her age using assumptions about how old she may have been at the time. That is not a reliable method.
Without a confirmed date of birth, it is better not to present a precise age as fact.
This is especially important in celebrity biography content, where one incorrect date can be copied across many websites.
The most accurate approach is simple: Adda Quinn’s exact birth date and current age remain publicly uncertain.
Why Adda Quinn Stays Private
One of the most noticeable things about Adda Quinn is her private lifestyle.
She has not developed a public identity as an influencer, author, entertainer, or celebrity personality.
There is also little evidence of a widely verified social media presence where she shares details about her life.
Her privacy makes sense when viewed in context.
When she married Larry Ellison, he was not yet famous. Their relationship ended before his biggest business success. Quinn therefore did not begin her adult life as the spouse of a public billionaire.
Later, when Ellison became famous, she had already built a separate life.
Her low profile suggests that she never wanted her identity to depend entirely on her former husband’s success.
Adda Quinn’s Public Image
Adda Quinn’s public image is based mostly on privacy, independence, and her historical connection to Larry Ellison.
She is not known for scandals, public disputes, celebrity interviews, or attempts to remain attached to Ellison’s fame.
Most articles about her are created because readers researching Larry Ellison eventually become curious about his first marriage.
This means her public identity is unusual.
She is known, but not truly a celebrity.
Her name is searchable, but her personal life remains mostly outside public view.
That distinction should be respected when writing about her. Lack of public information does not mean there must be a hidden story or controversy. Sometimes it simply means that a person has chosen not to make their life public.
Why Adda Quinn Gets Attention Online
The reason Adda Quinn gets attention online is easy to understand.
Larry Ellison is one of the most famous figures in modern technology. When people research his biography, they often search for information about his marriages, former wives, children, and life before Oracle.
Quinn naturally becomes part of those searches.
There is also an element of contrast.
Ellison has lived a highly visible life, while Adda Quinn has remained almost entirely private.
That difference creates curiosity.
People want to know what happened to the woman who knew Larry Ellison before Oracle, before global fame, and before billionaire wealth.
The limited amount of confirmed information can make readers even more curious.
Adda Quinn’s Net Worth
There is no reliably confirmed public net worth for Adda Quinn.
Some celebrity biography websites publish estimated figures, but those numbers should be treated carefully unless they are supported by financial records or other credible evidence.
Larry Ellison’s wealth should not be used to calculate Quinn’s finances.
The couple divorced in 1974, years before Oracle was created and long before Ellison accumulated the fortune associated with him today.
A person’s former spouse becoming wealthy decades later does not automatically establish that person’s financial position.
Quinn’s income, investments, property holdings, and present financial situation remain private.
For that reason, any exact Adda Quinn net worth in 2026 should be viewed as speculation unless reliable documentation is provided.
Where Is Adda Quinn Now?
There is limited verified information about where Adda Quinn is today.
Some biography profiles connect her later life with Northern California, but a precise current home or address is not reliably established.
Quinn appears to have remained outside the public spotlight for many years.
There are no major recent interviews, television appearances, or widely confirmed public projects connected to her.
As of 2026, the safest description is that Adda Quinn remains a private, low-profile figure whose name receives attention mainly because of her historical connection to Larry Ellison.
Her lack of visibility should not be treated as a mystery.
It simply reflects a life that has largely remained outside celebrity media.
Verified Facts and Online Claims About Adda Quinn
Because so much information about Quinn is repeated across biography websites, it helps to separate better-established facts from uncertain claims.
| Claim | Status |
| Adda Quinn was Larry Ellison’s first wife | Well established |
| They married in 1967 | Well established |
| They divorced in 1974 | Well established |
| Their marriage lasted about seven years | Supported by the dates |
| They met around Berkeley | Commonly reported in established biographies |
| Quinn had a career connected to research management | Widely reported |
| She was associated with EPRI | Reported by multiple secondary sources |
| Her exact birth date is known | Not reliably confirmed |
| Her exact current net worth is known | Not reliably confirmed |
| Her precise current residence is public | Not reliably confirmed |
| She helped found Oracle | No reliable evidence |
| Every detailed divorce story online is verified | No |
This distinction matters because online repetition can make weak claims look stronger than they really are.
Adda Quinn’s Life Away From Fame
Adda Quinn represents a quieter side of stories connected to famous people.
She was married to someone who eventually became one of the biggest names in the technology world, but she did not appear to follow him into public life.
Instead, Quinn seems to have built a separate identity through professional work, research management, and privacy.
That choice is important.
Being connected to a billionaire does not automatically mean someone wants publicity.
Quinn’s low profile shows that a person can remain part of an important historical story without making celebrity attention the center of their life.
Final Thoughts
Adda Quinn is best known as Larry Ellison’s first wife, but her story is more than a footnote in the Oracle founder’s biography.
She married Ellison in 1967, before Oracle existed and before he became a famous technology billionaire. Their marriage ended in 1974, and their professional lives later moved in very different directions.
Quinn has been associated with EPRI, research management, and environmental work, while Ellison went on to build his career in software and databases.
What makes Adda Quinn interesting today is not scandal or constant publicity. It is the contrast between her quiet life and the enormous fame later achieved by her former husband.
Her exact age, net worth, and current residence remain uncertain, but the better-documented parts of her story show a woman who appears to have maintained professional independence and personal privacy long after her marriage ended.
