Anna Clark did not die in 1767. That was the year of her grandfather's will. (See https://www.americanancestors.org/sites/default/files/2022-06/regis... page 134.)
From Manchester (Mass.) VR, we can verify her birth. There is also an entry under marriages - (FORSTER (Foster)) Anna, and Samuel Clark, May 1, 1770." After some work, Samuel is in Geni - Samuel Clark
Any verification of who the Anna Forster (perhaps it should be Foster?) who married Samuel Clark would be great.
