Stuveysant Avenue is the correction location. My grandfather, Albin, came to America with his brother, Arno, (sometimes referred to as Arnold) to work for their Uncle Max Friedrich and train as butchers under his direction. I believe they left 3 more brothers and 2 sisters in East Germany when they came here. As indicated their father's name was Richard Friedrich and their mother's name was Agnes Wege.
Are you related to either of the two gentlemen, Max or Arno, or perhaps another extension I am not aware of?
