I am trying to find out more information about my ggg grandfather Friedrich Ferdinand Haese who emigrated to South Australia from Stettin, Prussia in 1849 (give or take 2 years). A published family history book said that his last name was changed from Hase to Haese after arriving in Australia however I have found no sources to verify this. A ship listing documents a Hase that may be him, but other ship listings around the same time document similar possibilities (e.g. Hesse and Haase). I know he was born 5 Jun 1822 in Stettin Prussia and his name is documented with different variations of three first names: Carl Ferdinan Friedrich in Australian records. Does anyone have any helpful resources, tips advice etc on how to find out more about this guy please?
