This is not my line but you might take a look at the 1850 census for Rutherford Co., TN. p.32/HH 1173 - There is a "Stanford" O'Kelley b.1815 NC; wife Narcissa b.1821 TN; son William M. b.1845 TN; daughter Martha J. b.1847 TN; and son Andrew b.1850 TN (2 months old). The names are similar enough that it might be yours. I am not sure how clear the ages were because I recorded it a number of years ago (and the information could have been given by a neighbor?). A Robert P. Leder is also living with the family. Hope this may help. Good luck.
