Kelly, Kent, Ronan (Roonan), Daly, Conway, Kenney (Kinney), Mulbrandon

I am searching for any information regarding any of the surnames. (They are all in my family tree). We believe that John Kelly and Bridget Kent Kelly had a son Patrick in 1842. He was purportedly an early Sein Feiner and family lore has it that he had to "stow away" on a ship to America because of his activities. Story has it that he blew up/burned a barracks of English soldiers. Patrick married Ellen Daly in Davenport, Iowa in 1869 so I am guessing that Patrick emmigrated in 1858 or so. Mary Ronan Daly is my great great grandmother. Her great grandaugher, married her grandson. Patrick Kenney emmigrated to Rock Island, Illinois and married Margaret Conway, whose father was Patrick J. Conway. We are trying to confirm. Also we have a wild card of Margaret Glinney Brew O'Neal who emmigrated with Mary Mulbrandon in 1871. They were listed as cousins. I cannot find the cousin connection. We know that Margaret Glinney stayed in close contact with the Mulbrandon kids and that Margaret raised one of Mary's daughers after Mary died in 1887. Any information on any of the surnamse of cast of characters would be helpful. Namsate
