Gillomaurus, Gillomanius, Gillomen, Guillomer

The King of Ireland when King Ambrosius Aurelius ruled in Britain.

Gilloman heard that Uther and Merlin had landed in Ireland to take away the Giantsí Dance (Stonehenge) from Mount Killaraus. Enraged, Gilloman assembled his soldiers and attacked Utherís party as they headed toward the Mount Killaraus, but Uther was victorious.

Gilloman later allied with Vortigernís son, Pascentius (Paschent), in an attempt to conquer Britain from Ambrosius. They met Uther at Saint Davidís (or at Menevia) in Wales, and both Gilloman and Pascentius were killed in the battle.
