Mo Chonna, Do Chonna (ns)
These names probably derive from Columb. Here they are separated from Columb, Colmán, Commán, Mo Cholmóc etc (ns) because they (Mo Chonna, Do Chonna (ns)) have a medial 'nn' which invites confusion with another group - Conna, Conóc, Mo Chonóc, Conan, Cynan (ns)- which may, rather, contain the element con, 'dog, hound'.
