Join the roomColmán Már mac Diarmato was an Irish king, son of Diarmait mac Cerbaill. Early sources and older scholarship distinguish two sons of Diarmait, Colmán Már and Colmán Bec, although some scholars suggest there was only one Colmán mac Diarmato. There are some traces of Colmán Bec in the Irish annals, but so far as Colmán Már is concerned only his putative death is recorded.
