The daughter of Thomas Barrett and his wife Elizabeth Stow and the sister of Lydia (who also married into this family) was born 12 Jun 1677 in nearby Sudbury. She married Zoroable on 4 Feb 1728/9 in Marlborough. As her parents are buried in Spring Hill cemetery, they must have moved to Marlborough at some time.
Elizabeth died in 1770 before her husband. She was 67 years and 10 months as we can see by this clip of the carvings. She is buried alongside her husband in the Old Common Cemetery in Marlborough, Middlesex, MA
The epitaph or verse on Elizabeth's gravestone is the one that appears (in several forms) on so many New England gravestones.
