I can't say for certain that the following is your James Bartley or not. Here is what I found recently as I was searching for my Bartley family in the 1850 Scipio, Meigs Co., Ohio, Census. P. 20, Line 34.
Elizabeth Bartley age 43 (no father's name given) Joseph Bartley age 17 Sarah Bartley age 16 July??? Bartley age 14 James Bartley age 12
I hope this helps some. They are probably related to my Bartleys - John Bartley and his wife Sarah F. ???
