In the 1861 census ofSt Mewan (near St Ewe), at Sticker, Ann Tyack, 31, born at Creed, husband abroad, had five children born at St Ewe : Joseph, 11, William, 9, Edward, 7, Mary, 2, and George, 6m. Exactly the same ones as those given in this forum by Angela Tempest, and four ofthem given by you. We can assume that Ann is Ann Barbery, William Tyack wife. At the very same place (Sticker), John Tyack, 56, miner, born at St Agnes, and his wife Mary, 53, still had three children with them : Susan, Nancy and Elizabeth.

In the 1841 census of St Agnes, at Goonvrea, John Tyack, 35, copper miner, and Mary Tyack, 35, had John, 15, William, 13, Mary, Jane, Elizabeth, Susan and Eliza. William, 13 years old, is probably the same who will marry Ann Barbery and live in 1861 at Sticker, in St Mewan, close by his parents, John and Mary. John Tiack, 25, tin miner, born in St Agnes, probably the elder son of John and Mary, lived also in 1851 close by his parents, with wife, Grace, and infant, Thomas.
