I found William HARRY 59 wife Emaline 30 sons Henry 13, John 10, Godfrey 7, Leonard 6 and Madison 4 in the 1870 Dist.1 Appling Co., Ga census. Probably your William Harvey and more of Henry's brothers names. I searched William born abt 1810 GA in Bryan then Appling Co., Ga. Happy hunting and just think outside the box when researching, follow siblings and watch for mispellings and switching between first and middle names.
