In 1870 the Womack surname was incorrectly indexed as Hamach. Looking closely at the census image, one can plainly see the surname is Womach. This is Burgess Harrelson "Harrel" Womack, his wife, Mary Elizabeth Potter, and their children born prior to 1870.

John was first counted on the 1870 Warren Co., TN census in the household of his parents.
