David, It is believed, but not absolutly proven as far as I know that Mary James' parents were Jesse J. James (not the out-law) b. abt 1802 SC, TN, AL according which Census you want to take; and Nancy Branch Lowe b. 1800 in Lincoln Co., KY.
Have I sent you their children?
They were in Anderson Co., Texas in 1850 and 1860, in 1870 and 1880, they were in Trinity Co., TX. I don't know where Mary Ann James Pharr is burried or when she died.
