I am looking for information on Frederick Black, Sr. and Jr. who lived in Botetourt County about 1790. Frederick Black was originally Frederich Schwartz. Frederick Sr. died there in 1817. Frederick Jr was married to Susannah Snider in 1804. Other names appeared on documents executed by Frederick Black as witnesses, John Black and Christian Black. Where do the fit in to the family? I would also like to know Fredrick Sr's wife's name and the names of their children, and anything else that fits in.
