Ginny, I took a look at the 1880 census ( LDS CDs) for Buffalo. There were about eight Burkhard families there then. One of the heads was a Simon Burkhard b.1815 Germany. One of his sons is named Charles. There are also Burkhards named George & John. I can send these entries to you if you think it would help. There were no Pischkes in Erie Co. in 1880 & although there were Paschkes none were old enough to be your Genevieve`s parents.
