Morton cites Benami and Squire J as sons. Other sources place both as sons of Henry Jones Blagg and Phebe Fox. Tend to surmise that those are correct parents.
Morton says Benami H married Sarah E Samples in 1872 but this seems to be Benjamin Hensel 1847 son of Henry Jones Blagg
Henry is a nephew and the son of Wm’s older brother Abraham
