The about of this Sarah states:
According to source below (see link):
Birth Date 6 Feb 1642
Birth Place Ipswich, Essex, MA
Death Date 3 Feb 1679 Age: 36
Death Place Ipswich, Essex, MA
Father John Whipple , M (1617-1685)
Mother Sarah Unknown , F (1624-1666)
Now that would correspond to her birth year. The problem is that the current John Whipple is probably a different person, as his timeline is, currently making him a father at 10 years of age (and the mother 9 years of age).
John Whipple (Lieutenant)
BIRTH: 6 Sep 1632, Bocking, Essex, England
DEATH: 22 Nov 1695, Ipswich, Essex, Massachusetts
I suspect that this Lt. John Whiple has been merged wrongly or that a different one should be the father of this Sarah.
