Sorry, I know nothing of Mary. I have always thought her name was Maria, not the Maria we have today, but as a corruption of Mariah as I found her in MO. I did find my William in Greene Co., Indiana, 1850, as a 2 year old with father James. Looks like James' father was one the the many Francis. There were several Bartleys listed adjacent to each other on the above census. Good luck.
