What exactly is required to be part of such? I'm an English-speaking Australian of mostly English and Scottish ancestry, with some Swedish thrown in.
I don't have German roots, that I'm aware of, anyway, but have cousins who do, so I've added a profile for one but stopped where it required research in Germany. (He was born Breslau, Silesia, Prussia.)
I don't speak (I did learn a couple of Christmas carols phonetically some 20 years ago) or read German, although I can pick out a word or three every now and then. (I can use an online translator!)
