Navajo Brady's 1900's

looking for for the family tree of the Brady's on the Navajo Nation.I am the son of Thomas Brady Sr. and grandson of Braided Hair.The story is that my father's last name was Braided Hair and when he was put in boarding school a Irish catholic priest changed it to Brady.That my father's mother Asaa Tabahii came from Red Valley/Cove area to Lukachukai.I know that the name Brady is Irish so I call myself an Irish Navajo.
