I really don't have any more info than you on Mendell but I have his father as Mellville not Mellvin. Mellville was the son of Samuel Roby Kisner and Elizabeth Pyles. Mellville had the following brothers and sisters. Sisters Setriah,Virginia, and Helen. Brothers George,Sam, and Calvin. I am descended through brother George whose son was John M. Kisner who was my grandmothers father, her name was Ardith Asenith Kisner who married Johnnie Willam Bryan. I am the daughter of their son Ernest Andrew Bryan.
