C F BOSTROM,went down w ship off Sitka

One of my Father ´s Uncles went down with his
ship in a storm off the coast of Sitka,
Alaska. He is supposed to have been a mate
in that ship. The whole crew went probably
down with it.
His name was Carl Fredrik Bostrom and he was
born on 5 November,1870 in Halmstad, Sweden.
According to the Ministry of Foreign Affairs
in Sweden it probably happened before 1920.
Does anyone know about this disaster and can
connect the ship ´s name with the person.
