This Mary Davies shares a tombstone/grave site with daughter Cynthia Ann Davis b. 1828 NC d. 1901 Parke County, Indiana.
Cynthia's documents always state her maiden name as Davis.
There are many Davies and Davis families in that area.
Many of the same families spelled the name differently.
I have been told that the name was spelled Davies in Wales and Great Britain. In the USA it was changed to Davis.
Background on Cynthia Ann Davis is that she married Zemeriah Lamb in Wayne County, Indiana in 1846. They then moved to Parke County, Indiana. Zemeriah was married before because there are older children in the household. Cynthia and Zemeriah had numerous children (some of them are not on census recordsL. They divorced sometime between 1865-1867. Census records list Cynthia as divorced. Side note: I have been trying to find records of this divorce.
Zemeriah Lamb then married Susan Ann Nance Benedict. She was the widow of John Benedict and had children from that marriage. They then had numerous children together.
I have no information on the father of Cynthia Ann Davis.
There are numerous Mary Davies in that area and other areas.
The tombstone only says Mother Mary Davies Age 80. It is listed on Find a Grave.
Mary Davies would probably have been born in the late 1790s to 1800-1810 because Cynthia was born in 1828.
I am hopeful someone has more information.
I have looked at various census records and there are several Mary Davies in that area. It is possible that she was married multiple times and had different names.
