As far as I can tell, my great-grandparents were Mathias and Christina Flesch who immigrated from Prussia(?) to Buffalo, NY sometime in the 1870's. The only children I can discover were Henry and my grandfather, Laurence who was born in Prussia(?) in 1874.Laurence married Adelhaide Spriesch(1879-1930) in Buffalo,NY in 1897. Their sons were Matthew,Charles, Leroy, and my dad, George(1913-1962).Their daughters were Theresa, Adelaide, and Irene, who is living in Rochester,NY.Can anyone help me with the missing pieces?
