Cornelius Bigelow and daughter Mary

Does anyone out there have any info aboutMary Bigelow who was the daughter of Cornelius Bigelow and Mary Graves? She was born at Marlborough, MA in 1734 and married Jonathan Cook at Westborough, MA in 1758.They were my GGGGGgrandparents. They had at least three children, Mary born in 1759,Jonathan born in 1760 (my GGGGgrandfather) and Luther born in 1764. Jonathan and Luther moved to NH in the 1780s and their sisterMary may have remained in MA. with their parents,I cannot find another thing as to what happened to Jonathan and Mary Bigelow, or if they had other children besides these three. Does anyone have a clue? Thanks for any info.
