I have TWO William Brocks in my file. One was born in Sevier county TN to James Jefferson Brock and Martha Catlett in abt 1859.
The other is a William Brock, born most likely in Jefferson TN. He was born abt 1881. His father is Wilburn C Brock and Mary Jane Shewbert. Wilburn is the brother to the former William. So I am assuming its a family name. Wilburn's William Brock moved with him to Banks County Georgia. As of now I don't have any other info on him other than he still lived with his parents in Maysville, Banks Ga. in 1910 at the age of 29.
