I don't know. According to 1850 census. Thomas was born in SC.If Thomas Kirkley and Isabella Jane Murchison are John A. Kirkleys aunt and uncle. Then Thomas and Asa Sr could be brothers.The Thomas Kirkley in the 1810 census had 3m under 10, 2m 10-16, 1m 16-26, 1m 26-45, 1f under 10, 1f 10-16 and 1f 26-45.So they had children that could be Thomas, Asa and Eli.I don't know how you connect that unless someone has data. I was looking in other states and found an Asa in Harrison, Virginia in 1830 census.You might want to look at that.
