I found Linesville Cemetery references to Margaret Edwards Stephens Largent giving her parents' names, Evan and Mary. The Linesville Cemetery also lists the same James Largent married to a Margery Keener, but in that case Margery's parents are not listed.
The website www.werelate.com surveys the references to Margaret Edwards Stephens Largent, showing a number of names including Post, etc. Some references (including Linesville Cemeter) list one previous husband as Hiatt; Stephens also appears to be married name. Who should figure out her LNAB and correct it if need be, on wikitree? Who is the mother of John Largent?
