My gr aunt Bertha told me that Margaret Gardner was full blooded Indian. Half Cherokee and half Shawnee ( I forgot the other but a cousin said it was Shawnee.) I have talked to Harold and Claude Patton(her brothers) They don't know how much or what kind.My Aunt who is daughter of Esther and my Dad don't know how much either. According to info we have been finding, Matthew Gardner was German so Margaret could not have been full blooded. If you are related to Mark Prow then I'm sure we have the same info.
