Notes:
Data source is the 1990 book, "Moomaw-Mumma-Mumaw-Mumaugh Genealogy" compiled by Robert Austin Moomaw (deceased).
The two wives of Edward Mumaw are somewhat speculative and not proved! It would appear that he married Laura Barger and they divorced.
"Greg Tucker" provided the following newspaper information proving the divorce
