I believe that Richard Nathaniel and his brother Joab A.were sons of Thomas but have not found proof. Joab A. Ainsworth,b.1795,was a brother of Richard and there is proof of that. The LDS Family History Center has some confusing information about Richard. They list; Richard,b.1798,SC and Nathaniel,b.1802 SC,as sons of Thomas and Sarah. My branch is from Thomas' son, Sampson Jefferson Ainsworth.
