I think my father and your husband are cousins (and me too!)
According to what my grandmother wrote:
Gideon Bud Corneil married Maude Myrtle Hollibough on July 3, 1900 in Hicksville,Ohio. They had eight children Bessie, Earl, Elmer, Jennie, Lucille, Mildred, Dale Ford (Buddy), and my grandmother, Bonniebel (Bonniebelle).
If you check out the Slope County,ND 1920 Federal Census u will find this....

They had three children Dale Hall Campbell (Deceased), Ruth Gail Campbell and my father, David James Campbell (birth certification says James David Campbell)
My father married my mother, Charlotte Ann Egbert and divorced. They had two children Darrell James Campbell and me, Jacinthe Donia Campbell. Both my brother and I never had children.
