Becket was born about 1119,[4] or in 1120 according to later tradition.[1] He was born in Cheapside, London, on 21 December, which was the feast day of St Thomas the Apostle. He was the son of Gilbert and Matilda Beket.[note 2] Gilbert's father was from Thierville in the lordship of Brionne in Normandy, and was either a small landowner or a petty knight.[1] Matilda was also of Norman descent,[2] and her family may have originated near Caen. Gilbert was perhaps related to Theobald of Bec, whose family also was from Thierville. Gilbert began his life as a merchant, perhaps as a textile merchant, but by the 1120s he was living in London and was a property owner, living on the rental income from his properties. He also served as the sheriff of the city at some point.[1] They were buried in Old St Paul's Cathedral.
