In 1898, a number of Indian tribes from New York joined together for the purpose of suing the U.S. Government. The suit involved a broken treaty (imagine that ;) ). Not only did they win the right to sue, they actually won the case and where awarded a sum of money as compensation. The money was to be distributed amongst the members of the tribes (including the Brothertown Tribe).
In order to properly distribute the money, the government requested individuals fill out applications to prove they had a right to settlement distributions. These applications are an incredible source of genealogical information. Thanks to the kind generosity of Caroline Andler of the Brothertown Indian Nation, I have a copy of the Application filed by Thomas Laton Kindness as well as one for his son, Purcell.
