My husband is the 1/2 second cousin once removed from Darius.

For Darius to be 1/8th Indian, one of his great-grandparents had to be full Indian. I do not have the names of the Castleberry great-grand parents. Just an allegation by Mrs. Walsa Box Castleberry that the male was "one of seven brothers who came over from Ireland or England." Nothing mentioned of the great-grandmother.

Isaac Cahal Morris and Susan F. Wortman (not Indian)

Andrew Jackson McBride and Nancy Ducan Hensley. (not Indian, the closed mention is tha Nancy's second husband, a step-great-grandparent was part Indian)

Eli Modglin, and Missouri Horn. (I don't have any additional information about his couple>)
