Gillafin Mac Coulahan

Gillafin mac Coulahan lord of Síol Anmchadha, 1096-1101.

Gillafin was a member of the Síol Anmchadha dynasty and one of the few members of the Coulahan clan to merit mention in the Irish annals. He succeeded to the kingship of the area upon the death of Madudan Reamhar Ua Madadhan, but was killed by the latter's son Diarmaid Ua Madadhan in 1101.

Among Gillafin's descendants were Professor Nicholas Colohan (1806-1890) and Arthur Colahan (1884–1952).
