Your John may be my 1st cousin, three times removed -- I don't have the paper trail to prove this, so I might be wrong. But, I do know that your grandma Sallie's father, John Peter Hodges, and her brother, D. Wilson Hodges, were Sheriffs of Franklin County (they were mentioned in a 1935 newspaper article about Bettie's testimony during the Liquor Trials; John had died by then). I don't know yet if any of Sallie's other brothers were Sheriffs.
John was listed as Peter Hodges in the 1900 and 1910 censuses, and as John P. Hodges in the 1920 census (he and his family lived in Franklin County, VA in all 3 censuses). John was a Farmer in 1900, a Deputy Sheriff in 1910, and Sheriff in 1920. Your grandma Sallie was age 7 in 1910, and age 17 in 1920. John's wife Bettie was listed as divorced in the 1930 census (in Franklin County; her son Wilson lived with her, he was age 21 and a Sheriff).
I'm not 100 percent certain, but it looks like John Peter Hodges was the son of the William Hodges who was the son of Albert/Elbert Hodges and Missouri Adaline Jones. And William's wife was Margaret Joyce, daughter of Allen Joyce (Joice) and Sally Poor (Poore). I have much info, so feel free to contact me for anything you might need.
