When Oliver Platt’s name appears in entertainment coverage, a quieter name sometimes surfaces alongside it — Mary Camilla Bonsal Campbell, the woman he married in 1992 and has built a family with over three decades.
Most people searching her name want to know the basics: who she is, how she’s connected to Platt, what she does, and why her name keeps appearing across celebrity pages and genealogy databases. This article covers all of that, using confirmed public sources and being honest about where the record runs thin.
Who Is Mary Camilla Bonsal Campbell?
Mary Camilla Bonsal Campbell is primarily known as the wife of actor Oliver Platt. She is a private individual — not an entertainer, not a public figure in her own right — which is exactly why her name can be hard to pin down across different sources.
She goes by Camilla. The New York Times used that name in its 1992 wedding announcement, and most casual references follow that lead. However, genealogy databases and celebrity biography pages often list her more formally as Mary Camilla Campbell or Mary Camilla Bonsal Campbell. These are all the same person — the variation just reflects different levels of formality across different types of sources.
Her name circulates because of her documented connection to Platt. She appears on his IMDb page, in People magazine coverage of his TV work, and in family-tree databases that tie her to his children. Outside of that connection, she has kept a low public profile.
Her Education and Early Career
The most reliable source for Campbell’s early biography is the New York Times wedding announcement published on September 13, 1992. It remains the clearest public record available about her background.
According to that announcement, Campbell graduated from Boston University. At the time of her marriage, she was working in New York City as a freelance assistant producer of documentary films. That detail tells us she had a professional foothold in media production before the marriage, even if the scope of that work wasn’t detailed further.
Her father, John P. Campbell, was connected to the New York law firm Curtis, Mallet, Prevost-Colt & Mosle. Her parents were from York Harbor, Maine, which also explains the New England setting of the couple’s wedding ceremony.
No verified information exists about her professional work after 1992. It would not be accurate to describe her current occupation, and this article won’t attempt to guess.
The 1992 Wedding and What Public Records Say About It
Oliver Platt and Camilla Campbell married on September 12, 1992. The ceremony was held at the First Congregational Church in Kittery Point, Maine — a coastal town not far from York Harbor, where her family had roots.
The New York Times covered the wedding announcement the following day, on September 13, 1992. That piece is where the most reliable details originate — the location, the date, her name, her education, her career at the time, and her family background. IMDb also lists the marriage date as September 12, 1992, which lines up with the newspaper record.
The announcement referred to her as Camilla Campbell, which is why that shorter version of her name appears in so many follow-up references. Anyone searching for her under different name combinations is likely tracing back to that same original source.
By any measure, the marriage has been a long one — over 30 years and counting, which is notable whether or not someone is connected to the entertainment world.
Their Three Children
Oliver Platt and Camilla Campbell have three children together: two daughters named Lily and Claire, and a son named George. People magazine and IMDb both confirm the three-child family.
Some genealogy databases list the daughters’ names with slightly different spellings — Lilly instead of Lily, and Clare instead of Claire. These are likely just spelling variations across different record sources, not references to additional children. Genealogy databases can be useful starting points, but they’re best treated as secondary references rather than definitive records.
All three children have been raised outside the public eye. Neither Oliver Platt nor Campbell has made their kids part of any public-facing presence, and available coverage consistently notes that the family has kept things private. The children are not public figures.
Oliver Platt — The Celebrity Connection That Brings Her Name Into Searches
Understanding why Campbell’s name appears so widely starts with understanding who Oliver Platt is. He’s a veteran film and television actor with a career spanning more than three decades.
Platt has appeared in a wide range of well-known productions. Film audiences may recognize him from movies like Bulworth, Flatliners, Lake Placid, and 2012. On television, he’s perhaps best known for playing Dr. Daniel Charles, a psychiatrist, on the long-running NBC drama Chicago Med, which has kept his name in entertainment coverage for years.
He also comes from a prominent family. His father, Nicholas Platt, was a U.S. diplomat and ambassador. That background added a layer of public interest to his profile even before his acting career took off.
Because Platt is regularly covered in entertainment media, any biographical profile of him eventually mentions his wife and family. That’s the main reason Campbell’s name surfaces in searches — she’s part of the factual record around a well-known person, even though she isn’t a celebrity herself.

Why Her Name Appears in Genealogy Databases
Campbell’s full name — Mary Camilla Bonsal Campbell — appears in several online genealogy and family-history databases. This is fairly common for spouses and family members of public figures. Once a name is attached to a documented public record (like a New York Times wedding announcement), it tends to get picked up and cataloged in family-tree tools.
These databases can include useful data points like names of children and marriage dates. However, they also sometimes introduce spelling variations or record discrepancies, as noted with the children’s names. Always cross-check anything from a genealogy source against a stronger reference — in this case, the New York Times announcement is the gold standard for her basic biography.
Her full formal name, Mary Camilla Bonsal Campbell, is the version most likely to appear in these databases. Her married name, used in entertainment coverage, is simply Camilla Campbell or Camilla Platt in some informal references. None of these differences indicate separate people.
What Is and Is Not Publicly Known
It’s worth being clear about the limits of the public record here. What is confirmed:
- Her full name is Mary Camilla Bonsal Campbell; she goes by Camilla.
- She graduated from Boston University.
- At the time of her 1992 marriage, she worked as a freelance assistant producer of documentary films in New York.
- Her family is from York Harbor, Maine; her father was associated with a prominent New York law firm.
- She married Oliver Platt on September 12, 1992, in Kittery Point, Maine.
- The couple has three children: daughters Lily and Claire, and a son named George.
What is not confirmed in reliable sources:
- Her exact birth date or current age.
- Her current professional work or occupation.
- Her current residence.
- Any net worth figure.
- Any details about her personality, personal views, or private life beyond what public records document.
Profiles that go further than this — claiming specific wealth figures, describing her as a publicist, or attributing other careers to her — are not supported by verifiable sources and should be read with skepticism.
A Closing Note
Mary Camilla Bonsal Campbell is a private person who has remained largely out of the spotlight despite being married to a well-known actor for over 30 years. What the public record shows is straightforward: a Boston University graduate, a former documentary-film assistant producer, a wife, and a mother of three.
Her name appears in celebrity biographies and genealogy records because of her connection to Oliver Platt — and that connection is well documented. Beyond that, she has chosen a life away from public attention, and the available evidence respects that choice. What we know is clear. What we don’t know, we simply don’t know.
