Although Thomas Hamon was living in St Martin, Guernsey at the time of his marriage to Rosina Brimage in 1899, he was born in Sark and he's from the Hamon family that goes back to the founding of Sark in 1575. His parents were William Hamon and Anne Hotton of Sark. Thomas and his family can be found in the 1881 and 1891 Sark censuses.
