clarise on Family Tree Circles

I am a descendant of Philip Packer and Hannah Sessions who immigrated from England. Then Philip Packer and Ann Coates, James Packer and Rose Mendenhall, Aaron Packer and Hannah Johnston, Jehu Packer and Sarah Dow, James M. Packer and Wilhemina Boyer, James Irvin Packer and Fannie Mae Brickley, Dorothy Sylvia Packer Carrolus, Sylvia Arlene Carrolus Reilly Campbell. James and Rose died in Howard, Centre Co., Pa. and it appears the family remained there until James I. moved to Altoona, Pa. Hannah Johnston's parents are unknown to me as is Sarah Dow's mother. One of these people could be the Native American I am looking for. Please, can anybody help me?
