Five years have passed since you posted your message about William Everton on GenForum. I don't know if you're still at this email address, but I wanted to comment on a piece of information you provided that probably bears confirmation. Back in 2002, you wrote:
"4. Captain John Everton was christened on Jul 2 1677 in Charlestown, Suffolk, MA. He was married Dec 15 1686 in Charlestown, MA to Sarah Taylor (daughter of Richard Taylor of Yarmouth and Ruth Whelden). Sarah Taylor was born in 1662 in Yarmouth, Barnstable, MA. She died on Jul 31 1695. Captain John Everton and Sarah Taylor had the following children:"
There are a couple of idiosyncracies with that data. First, you have a 9-year-old getting married (John Everton would have been only 9 at his 1686 marriage if he was christened in 1677).
Second, my understanding is that the Sarah Taylor who died in 1695 was single. She left a will, leaving things to her siblings. So you should double-check your sources on this marriage between Sarah and John Everton.
