I am a descendant of Elizabeth Bacon and John Nuthall. She was b abt 1609.(This is from Sharon J. Doliante's book: Maryland and Virginia Colonials) My opinion is that she was a little younger. John was b abt 1615-1620. This would place her as a contemperary of Nathanial.
Nathanial was b 29 Aug 1620 and d 16 March 1690. He m Elizabeth Kingsmill and Anne Smith.
I have been researching Elizabeth a long time and have not found her parentage. Some say she was the d/o James and others deny it.
