I am researching the Underwood line for my bro-in-law. His direct line is from Joseph Underwood and his wife, Sarah (unknown surname). Their son was Dixon Underwood b. 1803 d. 1887 and his wife, Keziah Baker b. 1803 d. 1880. Then, Sarah Underwood b. 1829 d. 1911 married George Kile. Their daughter, Rachel J. Kile married a Bates first and then Henry or Harry M. Slater. Any information on the Underwood line would be helpful in terms of Joseph's ancestry. Thank you.
