Sarah Fraley is the daughter of Henry Fraley and Mary Turner. Sarah had Fulton out of wedlock. She is the sister to my ggg-grandmother Nancy Fraley. I have found the Clay family (Albert G., James M., George W., Mastin G., Rufus M. and William H. Clay) in the 1850 census in Russell Co., VA, in the 1860 census all are in Carter Co., KY, in the 1870 census all but James are in Carter Co., KY (James is in Wayne Co., WV), and in the 1880 census Albert G. and Georges widow Margaret are in Somervell Co., TX, Rufus M. Clay is in Cooke Co., TX, Mastin Clay is in Jack Co., TX and WIlliam and James Clay are in Raleigh Co., WV.
I'm sorry, but I do not know who Albert G. Clays parents are although according to the census he was born about 1805 in North Carolina.
PS. James M. Clay is the father to my grandma Nancy Fraley's son (out of wedlock) Rufus M. Fraley.
Hope this helps.
