I am new to family history research and especially native american research. I have received a file on some of my family which indicates an Indian Number. I would appreciate any assistance you can give in providing more information on them: My great grandfather was Hamett Ashbury Nichols, born May 1874. The indian number for him was 17465. His father was John Clifton Nichols, born abt 1811. The number for him was 17281. Thanks
