Good to hear that this is helping. I missed an entry in my book titled Record of Estates of Johnston Co. NC 1808-1822 by Elizabeth E. Ross:
Account of Estate of Patrick O'Quin, dec. Lamuel Lee, Admr. 12 heirs, each share 16"5'. (no heirs named) Comm: Isaac Williams, John Lee, Nathan Allen. Feb. Court 1808.
