I saw your post and am interested in the Dillehay's that moved to TN. Johanna E. Dillehay married Miles McKnight bet. 1829 and 1830 in Smith Co., Tennessee. A posting at the Smith County site inferred that her family may have come from Person Co., NC. She was born August 11, 1811.
I would appreciate any information you have. Please contact me at firstname.lastname@example.org
