The 1998 book "Gunsmiths of Maryland" by Hartzler & Whisker reports that George Rizer I owned slaves. I don't have information to confirm or deny the statement, but I do know that there is a published family tradition of a different George Rizer who supposedly was a slave holder from Hancock County, Maryland (no such county exists) who married Caroline J. Weaver and had a son Charles Rizer who was born circa 1829 in Maryland. The story, which is included below, is from in the 1893 book "Portrait and Biographical Record of Madison and Hamilton Counties, Indiana".
