This is Hinson/Gannon connection. However afraid it will not help on ancestors of William and Sarah- Warren DeCosta Jackson, bn 1836 Clayton, Al married Mary Alice Hinson, d. of Needham. Among their children was Charles Harrison Jackson who married Anna Fonda Jennings-- they had son Charles Clyde Jackson who married Doris Howell Gannon -- she was d. of William Ernest Gannon and Minnie G. Boland.--- William E. Gannon son of William Gaston Gannon and Mary Howell.This William son of William Gannon and Sarah Joyner.----- I descend from another son of Warren DeCosta Jackson.I have looked in Boston for William Gannon [this for a cousin].We never got beyond what is now known, and I don't think she is still pursueing this. Oddily enough WarrenDeCosta Jackson's father John Jackson was born in Barnstable, MA.--lived in Boston- Washington DC and finally in the 1830s Clayton, Alabama. No known connections Jackson/Gannon. I've started to look at the Hinsons again and hope to send some questions to K. Hinson soon. Thurman Hinson Jackson [Buddy] We may have corresponded in the past-not sure.
