HeritageQuest (Ancestry) Library version has the 1850 & 1860 slave schedules for the US census. As you probably know, it only lists owner's name and male/female slave by age.
1850 has Richard Corley but seems to be in Smith county. A lot of R Corleys appear as well.
1860 is a little more interesting. I searched for Sarah Corley (who would be the widow in 1860) AND Rappahannock County yielded 9 individuals. Judging from the ages it looks like a family (female + 7 kids) + 60 yr female.
I suspect a little digging could yield a will for Richard (d. 1854?) that probates property between widow and children?? . Might name some specific names that match the ages.
