I can find Wm. G. Venable's family, Nancy Crane died in Giles County, TN sometime after the 1860 census was taken. He married Mary Elizabeth Sudbury in Marshall Co., TN on May 23, 1865.
Wm. G. Venable was born Jan. 9, 1829 near Chapel Hill, TN in Marshall Co. This is from the widow's CSA Pension application which I purchased from the TN State Archives. He was in Co. G 35th Reg. Ala Inf. Tillman Brigade.
Callie Venable was a cousin to the Wm. G. Venable family. She was born 2-6-1855 in Athens, AL and died 1-7-1917 in Williamson Co., TN. Death certificate shows her father as James Venable and mother unknown.
I am afraid this is all the info I have on her. There was a Hargrove and Fry family who moved to Wm. Co. (Dist. #4) from Giles County about the same time the Venable family showed up in 1870 and I believe they were probably related thu a Tillman Holland family also from Limestone Co., AL and Giles County, TN in the Elkton area.
