I'm probably the guy that thinks the parents of Zachariah are William Langley and Mary Ann Anglin.
I have followed this William through several census years. In the 1830 Census he has sons that one would have would have been of age to have been Zachariah.I don't have at hand a complete analysis of the records.I will try to do that in a coming post.Soon.
Never the less I believe that this William Langley died sometime after 1840.In 1850 a Mary A Langley, age 70, of NC shows up in the household of Chesley Brittain in Tuscaloosa Co., NC.Two houses away from my 3rd ggrandfather, Osey Langley. I believe that Chesley's wife was Osey's sister and that Mary A had come to live with her, as was the custom of the time, when her mother was widowed.As we know, William is no longer found after 1850, and this would explain what happened to his wife.
I will try to make another post ASAP after I pull my records together and make the analysis.
