25 U.S.C. § 184

All children born of a marriage solemnized prior to June 7, 1897 , between a white man and an Indian woman by blood and not by adoption, where said Indian woman was on that date, or was at the time of her death, recognized by the tribe, shall have the same rights and privileges to the property of the tribe to which the mother belongs, or belonged at the time of her death, by blood, as any other member of the tribe, and no prior Act of Congress shall be construed as to debar such child of such right.
