I definitely remember addressing Christmas cards to your great grandparents at that address and did send them into the 1960s. We might have sent them to your great grandmother after your g/grandfather passed away. If anyone would remember the cards they would have been from Louise (my mother never used the name Aloysia her birthname), George and Susan Rose. I'm quite a bit older than you. I graduated for Washington High School in 1967! :)
No one talked much about the family history either in my family or maybe they didn't know all that much. My mom became the repository of family photos (not that there were a lot) since she stayed living with her dad until he died in 1944.
This is so exciting to be in contact with someone who crossed our family. I will help you in any way I can.
You can always e-mail me if you don't want to go through this board.
