GEORGE< GILBERT, CHARLES MOUAT
Found reference to above names in book "Undelivered Letters to Hudson's Bay Company Men on the Northwest Coast of America, 1830-57"Entry 61 page 240
Letter to George Mouat in Fort Victoria, Vancouver's Island from brother Gilbert Mouat in Couper St 47 Nort Leith, Shetland dated 14 August 1850.
Letter names brother Charles, that Charles wife has died, that one of Charles Children has died since this wife died leaving him with 2 children, that their sister Urlsa is staying with Charles but refuses to take charge, Their mother is mentioned( no name) but not their father. Also mentioned is the fact that Gilbert has "another daughter named Elizabeth"
George deserted on 31 January 1850 during the ship "Cowlitz" stop in Hawaii which is why he never got the letter.
Am no relation, just trying to help.
