Hope I'm not too late to reply to all of you. My grandfather, Carl Paul Brause, was the son of August Brause, who was married to Johanna Borowksi (both apparently of East Prussia). My grandfather had a sister, Eva, who married and had 4 children, one of whom I found in an obituary notice from 2009.
I am trying to find the towns/villages August and Johanna came from. I myself, was born in Minnesota and now live in London. The European roots of my family history is of particular interest.
