I am not part of the Ancestry DNA database. Hopefully one day.
And a follow-up....It does appear that Margaret Burton is indeed the daughter of Caleb Burton and Elizabeth Burton, as per her death certificate information I finally found on FamilySearch. I cannot pull up the original document. I added the screenshot as a attachment.
But she still really leaves me baffled as to how she suddenly appears and is born prior to the end of Caleb's first marriage and his subsequent marriage to her mother. Hopefully a copy of her obit will come up somewhere.
BTW...her name comes up a number of times in the Charlevoix County Herald on Chronicling America site as Mrs. Maggie Gilkerson. Please let me know if you find any more out on her.
