Also Garrison Sims lived in Cherokee County, Ga. in 1850 and 1860 and his widow lived there in 1870 and 1880. Although purely speculation, it looks as if George L. and Garrison "went back home" and married. As noted above, their land in Benton County, Al. sold in 1849 and 1851 for back taxes indicating they had left it. Ester Sims Stephenson, granddaughter of both B.H. and his brother Henry G. is said to have said that the Sims came from Georgia "because of a killing".
Research in Cherokee county, Ga. might prove fruitful.
