I found a William F. Simerell listed in the 1810 Tax List for Jefferson Co., TN.Also in Jefferson Co., TN, William Simerell m. Mary Whalen on 20 Mar 1820. Narcissus Simerell m. Daniel Hance 3-4-1824 in Jefferson Co. TN. Isabella Simerell m. Allen Sarrett on 26 Mar 1819 Jefferson Co., TN. I would suspect that William F. Simerell was the father of children Isabella, William, and Narcissus. In the will of William Simerell, we know he had a brother John Simerell in Holmes Co., OH who stated in the Census he was born in PA in 1796. So it looks like this family came from PA to NC about 1797/8. It might be helpful to find the will of William F. Simerell. Is anything here new to you? Do you have anything to add that I missed?Are you also working on the Whalens?
