I am also a descendant of a William Henry Carson (1861-1910) and was told by my grandmother that she was related to Kit Carson. My Carsons were in SE Tennessee (Bradley and Hamilton Cos.) in 1860 and 1870. William's father was C. E. Carson, AKA Caroline, and was in Benton (now Calhoun) county Alabama in 1850 with wife N.and an older female E. age 64. I believe E. may have been Esther Stone who married Andrew Carson in Blount Co TN in 1808. Do you have any info on the Carsons in SE Tennessee? Please email me at firstname.lastname@example.org.
