I am an enrolled member of the Shoshone-Paiute Tribes of the Duck Valley Indian Reservation of Nevada/Idaho. Although I do not recognize your ancestors name and there are no PRICHARDs on the reservation today, I can refer you to Laura Hull-Teller. She is in the enrollment office and may be able to tell you if your ancestor is listed on our base roll. Call (775) 757-2921 and ask for Laura and/or the enrollment office.
