Colmán
COLMÁN—VIII—Colman, Coleman; 'son of Colman' (a name in use in England in Anglo-Saxon times, but doubtless borrowed from the Irish. Searle gives it in three forms : Colman, Coloman, and Coleman, under the last of which it appears as the name of a landholder in the time of Edward the Confessor). A family of the name came to Ireland about the period of the Anglo-Norman invasion and settled in Dublin and other places in Leinster.
