Do you know the parents of Rhoda Baker Ayers (b. ca 1778, probably in Patrick Co, Va.)? She married Benjamin Ray Landreth Jr. (b. ca 1777, probably in Patrick Co, Va.). Their oldest child was Jonathan Landreth (b. 15 Feb 1800), who migrated from Virginia to Macoupin Co, Illinois.
Due to the similarity of names, I believe Rhoda Baker Ayers is the granddaugher of Nathaniel Ayers (b. 4 Mar 1700) and his wife, Rhoda Baker.
