Colonel the Honourable Thomas Talbot was born into an Anglo-Irish aristocratic family, on ancestral lands in Malahide, Republic of Ireland, which the Talbots had owned since the 12th century. He was born on July 19, 1771, the fourth of twelve children. At the age of 11, he was commissioned ensign in the 66th Regiment of Foot, British Army. In February, 1792, at 20 years of age, he was in Montreal with the 24th Foot when he was named private secretary to John Graves Simcoe, the first lieutenant governor of the new province of Upper Canada. With Simcoe, and later on Simcoe’s behalf, Talbot traveled extensively between York and Detroit, bounded by the Thames River and the Lake Erie shoreline.
