Charles:
We don't know if you've searched at the FamilySearch.org site, but here is an Arthur P. Fort, born in 1828 in Georgia, list with his family during the 1850 Federal Census:
"United States Census, 1850," index and images, FamilySearch (https://familysearch.org/pal:/MM9.1.1/MZY6-TGC : accessed 28 Dec 2012), Arthur P Fort in household of Owen H Fort, Washington county, Washington, Georgia, United States; citing dwelling 760, family 760, NARA microfilm publication M432, roll 87.
That is a great and free search site. (FamilySearch.org)
Good luck1
