Abigail was the second wife of Richard. She was the widow of Nicholas Follett, who was last mentioned in the records in 1663. There is little information on her online that I have found. Under Nicholas Follett’s entry in the GDMNH, it says she was +/-80 years old in 1706, making her birthdate around 1626.
Per the GDMNH, known children, all with Nicholas, were Phillip, Sarah (born c. 1654, m. John Meader), and Nicholas.
