When genealogy searches and celebrity family trees surface the name Jack Newton Ignatius Hall, most people are looking for one thing — his connection to actress Diane Keaton. He was not a public figure in the traditional sense. He did not appear on screen or hold a well-known public office. But his name keeps coming up because of who his daughter became.
This article covers what is actually known about Jack Hall — his life, his career, his family, and why different sources sometimes list different birth years. Everything here is drawn from confirmed genealogy records and publicly available biographical sources.
Who Was Jack Newton Ignatius Hall?
His full name was John Newton Ignatius “Jack” Hall. He was a private professional, not a celebrity, and his name appears in search results almost entirely because of his famous daughter.
Public records describe him as a civil engineer and real estate broker. He was born in Omaha, Nebraska, and later settled in Southern California. He died on September 1, 1990, in Corona del Mar, Orange County, California.
That is the short version. For most readers, those facts answer the main question. But there is a bit more context worth knowing, especially if you found his name through a family tree or a celebrity biography.
His Connection to Diane Keaton
Diane Keaton was born Diane Hall in Los Angeles in 1946. Jack Hall and his wife, Dorothy Deanne Keaton Hall, are her parents. That parent-child relationship is why his name appears in celebrity genealogy databases and biography summaries.
When Diane pursued an acting career, she needed a stage name. Another performer was already registered under the name Diane Hall. So she adopted her mother’s maiden name — Keaton — and that became the name the world knows her by.
This was a professional decision, not a sign of any family distance. The name change from Hall to Keaton is a documented part of her early career history. Jack Hall remained her father. His name simply stayed out of the public eye while hers became one of the most recognized in Hollywood.
It is worth noting how common this kind of situation is. Many celebrity parents are known mainly through their connection to a famous child, not through their own public biography. Jack Hall is a clear example of that pattern.
His Career as a Civil Engineer and Real Estate Broker
Multiple sources — including MyHeritage and memoir context from LitLovers — describe Jack Hall with the same two professional roles: civil engineer and real estate broker.
Both careers were well-suited to mid-century California. The state was growing rapidly in the postwar decades. Civil engineers were in demand, and real estate was an active field for anyone with connections to the building and development world. His dual career fit the time and place.
There is no public record placing him in a notable corporate role or civic position. He was a working professional — the kind of person who built a stable career and a family without seeking any spotlight.
His work background does give useful context for understanding Diane Keaton’s upbringing. By most accounts, she grew up in a stable, middle-class household in the Los Angeles area. That kind of environment — steady parents, professional father, suburban California — is often cited as a foundation in profiles of her early life.
Birth Year Discrepancy — 1921 or 1922?
If you have looked up Jack Hall in more than one place, you may have seen two different birth years: 1921 and 1922. This is a real discrepancy, and it is worth addressing directly.
The stronger genealogy sources — including Geni, Find a Grave, and a Hall family genealogy site — consistently list his birth date as February 6, 1922. These are the records that researchers and family history sites typically rely on for accuracy.
Some secondary sources list 1921, but those sources are not as well-documented. When a more carefully maintained genealogy record and a general secondary source disagree, the genealogy record is usually the better guide.
Small date discrepancies like this are not unusual. People born in the early 1920s lived before standardized documentation was widely enforced. Birth records from that era sometimes contain errors, and transcription mistakes can carry forward into online databases over time.
The safe approach is to treat 1922 as the better-supported birth year while acknowledging that some sources say 1921. Neither figure should be presented as absolutely settled.
His Family Background and Roots
Jack Hall was born in Omaha, Nebraska. WikiTree records name his parents as Chester Newton Hall and Mary Alice (Powers) Hall, which places his family roots firmly in the American Midwest.
He later married Dorothy Deanne Keaton Hall. Together, they had children, including Diane. His move from Nebraska to California follows a pattern that was very common in the mid-twentieth century. Many Midwest-born Americans relocated to the West Coast during and after World War II, drawn by economic opportunity and California’s postwar expansion.
His final years were spent in Corona del Mar, a coastal community in Orange County, California. That is where he died in September 1990.
For readers doing family tree research, the confirmed details are: Nebraska birth, California death, parents Chester and Mary Alice Hall, wife Dorothy Deanne Keaton Hall, and children including Diane. Beyond those confirmed points, deeper ancestry claims should be approached carefully and verified against reliable genealogy sources rather than taken from general celebrity profile pages.
Why His Name Keeps Appearing in Searches
It is worth stepping back and explaining why Jack Hall gets any online attention at all. He was a private man who lived a quiet professional life. He was not an actor, a politician, or a business leader with a public profile.
But Diane Keaton is one of the most well-known actresses in American film history. She has won an Academy Award, appeared in dozens of major films, and remained a recognizable public figure for decades. When people research her life or build out her family tree, her parents naturally come up.
That is the simple explanation for why his name surfaces. He is not famous on his own terms. He is notable because of who he raised.
This is a pattern worth understanding if you follow celebrity biographies or genealogy research. Parents, grandparents, and siblings of famous people often appear in searches not because of their own accomplishments, but because of their family connection. Jack Hall fits that description exactly.

A Private Man, a Famous Daughter
Jack Newton Ignatius Hall lived a life that most records describe in just a few lines. He was born in Omaha in 1922, built a career as a civil engineer and real estate broker, raised a family in Southern California, and died in Corona del Mar in 1990.
None of that would draw much notice on its own. But his daughter, born Diane Hall, became Diane Keaton — and that changes everything about why people search his name today.
What the public record gives us is a clear, if brief, picture: a Midwest-born professional who settled in California, married, raised children, and lived without seeking public attention. That is what is known. That is what the sources support. And for a man who clearly valued a private life, that may be exactly how he would have wanted it.
