Mary Grace Grayson (Grace) - Name

I haven't researched my Grayson line to this generation, so when I got the inconsistency notice, I looked to see what people have in their trees on Ancestry. Everyone seems to be listing this Mary Grace ad Mary Grace Jones. I see the note in her About section stating that it's uncertain if Grace is her middle or maiden name. It may be that she was born a Jones and Mary Grace was her given name.

Unless there is some documentation for her information, I don't think we can assume her maiden name was Grace. I Googled and couldn't find much on her at all. Wiki doesn't use the name Grace in her name at all and has her maiden name as unknown:

I did find a / another Mary Grace Jones from a different generation who was married to John Earnest Grayson, so not the same person:

https://ancestors.familysearch.org/en/L157-62Z/mary-grace-jones-164...

But I noticed that this Mary Grace Jones b. 1646, d. 1686 is the same person being attached as the mother of John B. Grayson on Ancestry, so folks are mixing them up, which 'could' mean that John B. Grayson's mother and the wife of his father Thomas Grayson wasn't Mary Grace anything and that Wiki just showing her as Mary (Unknown) Grayson may actually be more accurate.

The inconsistency showing on the profile of son John B. Grayson is:

John B. Grayson had a birth date after his parent's (Mary Grace Grayson (Grace)) death date.

If anyone has found any good documentation for more info on her than Wiki shows, please share that and put notes in her About section.

Thanks in advance for any assistance.
