Sorry, no idea how to edit here-it appears Amy and Agneta are the same person, d. 1577 https://familysearch.org/photos/stories/11763660
Thanks for pointing that out.
I'm not sure that Amy (or Amye) and Agneta are the same; I see many have distinctly different birth years for them, and Amy's birth year of 1547 would be a nice 'fit' to being married as Ambrose's Ambrosius Wyllys 2nd wife and as mother of Richard Richard Wyllys & Thomas Nathaniel Willis.
Those places I see Agneta & Amy as the same person also have a death date of 1572, so that doesn't seem to be helpful.
What would be helpful would be to upload some documents about the sisters and marriages, if any can be found.
FYI: There seems to also be debate about Amy & Agneta being daughters of William Coles vs. Richard Coles. Again, documents would help resolve this question.
