Gambon had married Lady Anne Miller, a retired mathematician, in 1962. Together they raised their son Fergus, who grew up to become a prominent ceramics specialist and regular appraiser on the BBC’s Antiques Roadshow. The marriage was grounded in decades of mutual respect, and neither party ever petitioned for divorce or formal legal separation.
Instead, Gambon established a dual geographic routine. He divided his time between the 4-million-pound 17th-century country house he shared with Lady Anne in Gravesend, Kent, and a modern townhouse in Chiswick, West London, where he lived alongside Hart. In 2007, Hart gave birth to their first son, Tom. Two years later, their second son, Will, was born. Gambon was 68 years old when his third child arrived. He ferried back and forth between Kent and West London in his beloved sports cars, sustaining both households without public disputes or domestic litigation.
