He grew up with his brother Blair and sister Karenin Ralston, Renfrewshire, where his father was the local minister. Two of Tennant's maternal great-grandparents, William and Agnes Blair, were staunch Protestants from County Londonderry, Northern Ireland, who were among the signatories of the Ulster Covenant in 1912. William was a member of the Orange Order. Tennant's maternal grandfather, footballer Archie McLeod, met William and Agnes' daughter Nellie while playing for Derry City FC. McLeod was descended from tenant farmers from the Isle of Mull. At the age of three, Tennant told his parents that he wanted to become an actor because he was a fan of Doctor Who, but they tried to encourage him to aim for more conventional work. He watched almost every Doctor Who episode for years, and he spoke to Tom Baker at a book-signing event in Glasgow. Tennant says he was "absurdly single-minded" in pursuing an acting career. Tennant was educated at Ralston Primary and Paisley Grammar School. He acted in school productions throughout primary and secondary school.
