How interesting that you have made so much progress. I wonder if we'll ever find out if our ancestors are related. Perhaps Bruss was just a very popular name like Smith is or used to be.
I can remember seeing a whole list of churches in the microfiche file but I wouldn't know where to begin. I've tried doing that with the Latvian church records and it is a big job indeed.
So, I will put something out on the message board for Pomerania and see what happens.
BTW, have you been to that part of the world or do you plan to go? I've been to Stettin once a few years ago. I was there for only a few hours but I found it quite interesting, especially to think that my ggrandparents knew the place so well.
