My grandparents were John & Edith (Eisenhauer) Gasper. John passed away Dec. 1975. He lived to be 88 years old. So his approximate date of birth is March 12, 1887. My mother Ellen Gasper Bishop said that his parents were John and Mary (Laux) Gasper. She wasn't sure, but thought her great-grandfather was also named John. I do know that my ancestors have originated from the Belding, Pewamo-Westphalia area.
