N.N. Mitchell

Edward Wellbourne married Elizabeth ___, widow of a Mitchell; she'd had one known child, Thomas Mitchell, by her first husband. (This relationship is proven by a document in which the administration of the estate is relinquished by Elizabeth to "her sons Thomas Welborn and Thomas Mitchell;" and this Thomas Mitchell is usually identified as the Thomas Mitchell who married Ann Teague, about whom more below.)

I'm looking for any clues to the parents or origins of Thomas Mitchell, b. ca. 1684, d. 1747 in Baltimore Co. MD, m. Ann Teague. In Robert Barnes' book "Baltimore County Families," he states that in 1730 Thomas Mitchell stated his age as 46 and said that he had lived in Baltimore Co. for 30 years.He first shows up on the tax rolls in Spesutia Hundred, Baltimore Co., in 1703. I know that his mother was Elizabeth ___ who remarried to Edward Wilbourne. If anyone has any information about Thomas' origins, I'd be glad to find out about it.I have a lot of information on his descendants which I'm happy to share.
