While her ancestry is presently unknown, Polly (perhaps Mary) Nedson was from the Eastern Pequot Nedson family from North Stonington, Connecticut, either by birth or by marriage. Her name appears on an 1839 Eastern Pequot petition to the New London County Court expressing their dissatisfaction with their overseer, Ezra Hewitt, and requesting he replaced with Deacon Charles Wheeler. She accepted tribal funds in 1832. From 1846 to 1850, Hewitt noted that she received four pairs of shoes, three dresses, and the material to make dresses. When Henry Shantup fell ill in the winter of 1851-1852, Polly provided him care from December 25th until February 1st, the day he most likely died. The last entries for her are in Isaac Miner's accounting in 1852.
