It is unclear whether or not this is the correct family. The information about them come from the Genealogical Record of Rev. Hans Herr & his Direct Lineal Descendants, T.W. Herr, Lancaster, PA, 1908, p. 370. In that listing the author records Mary J. Mumma's parents as Urias Mumma and Mary Muckle. I show his mother as Mary Ann Kindig. I checked the 1850 cenus and found a Mary Muckle living in Earl Twp of Lancaster CountyPerhaps Mary's surname was Muckle.
