Hi, my name is Henri Beerman (onlyone n) and I'm from Almere in the Netherlands. I was born and raised in Amsterdam, which is about 20 miles from where I live now. My ancestors all come from Amsterdam but the earliest one I've found was born in Warendorf Germany some 60 miles across the Dutch border in 1690 and his name was spelled with 2 n's. Goodluck on your research.P.S. When I was in Warendorf some 15 to 20 years ago, I noticed that there were still quite a few people named Beermann in the telephone directory.
