Question:

Anyone know of a Braun family in Pennsylvania?

Hi, I am doing a bit of family research, and find that the Brauns left the UK to operate in the coals mines somewhere in the State. Many, many years ago, but I assume that there must be living relatives.
I have checked some US records, but they run a bit thin after 1950.
Are you a Braun, or know of one ?

Bob - remote relative of the Brauns.
Pleased to receive any response.
