I wonder why his family left Breslau? Was it like leaving Boston for New York? It's about the same distance & with much more opportunity in the bigger city. His parents had little Hans & Charlotte (I can't remember if she was older or younger). Was it in-law trouble? Or maybe the relatives were in Berlin & Breslau was just a waystop?
My father's been gone almost 30 years, my oldest sister more than 10—who would know the answers to any of this? Frustrating but thrilling to have new questions. And why didn't I ever wonder about this before?
Update: My mother says Dad's father had gone to Breslau to work in a department store; they weren't from there. Also, his sister was older.
