Hi Sue,
I think that I may be able to help with this old query. Ludwig Abrahams emigrated from Danzig (Gdansk) in about 1870 with his wife and small family. Albert and Augustus were two of his sons. The family had farms around Blessington but the parents moved to Bruny Island. Ludwig died in 1916 and is buried on Bruny Island alongside his wife. I dont have all the details here with me, but can fill you in a bit more.
Regards, Ian Anderson
