My KING family from Iowa seemed to have a strong relationship with the McDonough family who lived in Iowa City Iowa and St. Louis MO. I think they were relatives, but have not confirmed it so far. There was a Lily McDonough whose name keeps coming up....everyone knew her and loved her, no one can say for sure if she was related. My KING and O'TOOLE family came from the same area of Clifden, Galway as your McDonoughs. Thought there might be a connection.
