She is not Charity the wife of David Jelliff who lived to be 105 years old, unless she remarried after David Sturges died, but I have not seen any evidence of this. She is also unlikely to be a native American (Pequoit Indian) as no DNA from those populations show up in my ethnicity on any of the online platforms that deal in such things (Ancestry, MyHertiage, 23 and Me, Family Tree DNA, etc.)

David Sturges married Charity in 1747. They had 13 children:
