MARBLE, Sarah, w. John [old age, CR1], [died] Apr. 29, 1809. [a. 97 y. CR1] [Birth about 1712. CR1=First Parish Church records]
By age at death, and marriage record calling her "Sarah French of Newbury", she appears to be Sarah French, d/o John French and Sarah Noyes, b. Newbury 12 Aug 1713. But there seems to be little coverage of this family, so no confirmation found.
