I'm confused.
This Sarah has 5 children listed.
Anne Cornell born in New York in 1657.
Denton Thorne born in Massachusetts in 1659.
John Thorne born in England in 1710.
Joseph Thorne born in England in 1712.
Samuel Thorne born in England in 1714.
So this Sarah - born in England in 1623 and died in England in 1681 - immigrated to New York, had a daughter, moved to Massachusetts, had a son, moved back to England and 50 years later - 29 years AFTER she died - had 3 more sons in England.
There MUST have been several Sarah Dentons because this list of children is impossible.
