I believe my great great grandfather's original last name was Schenkel. I base this on the fact my mother always said it was shingle or shengle, but she was not certain. I did find an Ed Rivers working for a Chris Hencke in Galveston, TX just the last couple of years before the storm that wiped out a good portion of Galveston in 1900. My great grandfather was a doctor and in places it says he is of Virginia, Missouri, Tx, etc. He was born in Scott County, Tn according to some records and his father was from Germany. I don't know at what point the name was changed or why but my Mother seemed to think they might have done something, possibly illegal, that forced the name change. Also my gr grandfather claimed to be a cousin of Dr. Thomas Willson, whose mother's last name had been Shangle. If any of this sounds familiar please contact me.
