Did the person who told you about Joel and Roxalana happen to give you a source for this info?
Earlier in the year I had e-mail from Beckie Rawdon.At that time, she did not have any info on Mary Jane, but since then seems to have taken my e-mailed query to her (same as appears on this GenForum) as gospel.She passed to me the same info you have here, but when I asked for her sources she made such elusive statements as "I don't remember," "will look it up later," "from WV history books."To date she has not been willing or able to come forth with specific books/records, etc.
Since I have Laidley's History Book, I know some of this info is in it, but he doesn't mention Mary Jane as a child of Joel, nor do any of the other history books I possess or have found in Gen libraries around the country.And, in spite of much Kanawha Co. courthouse correspondence, research into birth/death records, etc., I have not been able to find any verification of the parentage of Mary Jane. If I could be sure of it it would definitely fill in a hole in my research so, if you run across anything concrete, I would be most grateful if you would share the info with me.
