I am interested in Frederick Black Sr. formerly Frederich Schwartz, and Frederick Black Jr. Frederick, Sr. died in Botetourt County in1817 circa. Frederick, Jr married Susannah Snider there in 1804. I am also interested in Christian Black and John Black who witnessed documents signed by both Fredericks.Frederick Sr.was my great, great, greatgrandfather and Frederick, Jr. my great, great, grandfather. Any information on them or their families would be appreciated.
