John Whitfield

Marjorie's will in 1675 leaves everything to John Whitfield, orphan, and designates Clement Creswell as more or less the guardian for John. She calls Clement John’s father-in-law. Your father-in-law is your spouse’s father, but the assumption is John was still a minor so obviously he was not married. The use of the word father-in-law here meant something different to Marjorie. Then when Clement Creswell writes his will in 1682, he passes everything that Marjorie held on to John Whitfield. There were several men named Whitfield among the earliest settlers of Virginia.

In any event, John Whitfield must have been quite young in 1672, meaning that Marjorie could not have been Anthony’s mother, so John Herring must have been married earlier to someone whose name is not known.
