If your grandmother was an Indian, you may qualify for special federal education benefits, among other benefits. Proving your heritage through your grandmother is essential for claiming the benefits. Tribal records aren't perfect, but most tribes have a record of people born into the tribe after 1900. Find the correct information and legitimize your claim to Indian heritage. Keep a copy of the records proving your grandmother's tribal affiliation once you've located them so that you can prove it to any officials who ask.
Create a family tree, starting with the family members whose heritage you're sure of that are related to your grandmother. Go back as far as you can until you reach a point where there is no more information.
Look up birth records, marriage records and death records by contacting the Department of Vital Records and providing the required information and payment for a birth certificate.
Contact the courthouses in the area where you grandmother was born, where she lived and where she died. Ask for access to civil records. Give her name, social security number and personal information about yourself -- along with a fee -- to obtain copies of the records.
Contact your regional office of the Bureau of Indian affairs. Ask if they can assist you in a search for your grandmother's name on past rolls. Also inquire about information pertaining to tribes located in the area where she lived.
Contact the tribe in the area where your grandmother lived. Explain that you have reason to think she may have been a member of that tribe. Offer to let them see her birth and death records and to provide any information they need to validate or deny your claim.
