Ruth....I don't know that this necessarily has anything to do with William HENRY Davidson, but I note that the OLDER Joel Davidson (died before 1850; he was on the 1830 and 1840 Lincoln Co., TN censuses)....i.e., not the younger Joel Davidson who was incorrectly shown as "Jacob" by Ancestry.com and who married Miss Cody....married Elizabeth HENRY.Mrs. Elizabeth (Henry) Davidson was living as a widow in the home of A. J. (apparently Andrew Jackson) Davidson in Lincoln Co., TN in 1860 (and A. J. Davidson had been living in Elizabeth's home back in 1850).A. J. Davidson was in Independence, Arkansas by 1870, as I recall.A. J. fathered a son named William, but that son was born in 1860 (he appeared as an infant on the 1860 census) and not in 1861 like William HENRY Davidson did.Anyway, just thought that I would mention this.
