I don't have any info on your Mary Greer Jones, but you rang a bell with all the similarities to my road block. I am looking for the parents of my Mary Greer who was married to Samuel Jackson. Mary was born in 1793 in South Carolina, but she was living in Pickens County, AL in 1840 with her husband and 6 children. By 1850, Mary was a widow and is shown living with a son in Attala, MS and later that same year, she was back in Pickens with a daughter. She was in Falls County, Texas in 1860 with a daughter and she died there in 1884 at the age of 90. Perhaps my Mary Greer is related to yours.
