Mary Melton - Christening date?

If we don’t know her parents, how would we know her christening date? I annotated the “overview” with that comment and erased christening data from her profile.

Both the supposed birth and christening dates are too late for her to be married in 1653 and be the mother of Johan.

One of the notes says married twice, but gives the same name, Mary Melton, for both. So there was an unnamed first wife who was the mother of all the children except for Mary Boone.
