I am new to this and am trying to find Lisses. My grandfather-George-died in Morton Grove Il. in the early 60s. His parents died when he was very young and he was shuffled from sibling to sibling. His father was Benjamin or Bernard Liss and his mother was Matilde-I don't know her maiden name. They were from the area of Gdansk, Poland. His numerous brothers and sisters are listed above. I never knew any of them and don't know where they are. Any info would help.
Thanks,Greg Tredore
