I started writing a still-unfinished article on Dudley Russell Hooper last October when the original message about him appeared. Unfortunately, I still have heavy family obligations at present so I cannot take the time to post all of the available documentation. Still, I'll borrow some of the census info I compiled for my article and put into this reply.
I am confident that Dudley R. Hooper was the child of the man named Richard Hooper, b. 1790-1800 GA, who lived in Paulding Co. GA in 1840 and who moved to Alabama by 1860, when he was listed in Talledega Co., AL. I cannot locate the family anywhere on the 1850 census, but believe they may still have been in Paulding County in 1850. Significantly, there is a tie to Paulding County, Georgia in that Rebecca Watman, who later became wife of Dudley R. Hooper, was listed with her mother on the 1860 census of Paulding County, GA.
Here's the 1860 Alabama listing for Richard Hooper and other probable family members: 1860 Talledega Co, Northern Div, p. 805, #1296 R. Hooper 60 GA [m] A. 53 GA [f] M. J. 22 GA [f] B Hooper 17 Laborer GA [m]
The 17-year-old male is definitely listed as "B" Hooper, not as D or R. However, there is an 1866 state census for Talledega County where the head of household was D. R. Hooper and the family composition seems to show the presence of Richard Hooper, M. J. Hooper, Dudley R. and Rebecca Hooper, and their eldest son Richard.
The 1870 Jones Bluff, Coosa Co. AL mortality schedule shows a Richard Hooper d. Aug age 79 and MJ Hooper died Oct age 29 while in the household of D R Hooper.
I believe - but cannot yet prove - that this Richard Hooper who died in August of 1869 in Alabama is identical with the Richard Hooper who was named as a son in the 1815 Franklin County, GA will of William Hooper.
