Fingal is also a county in the Dublin-area in Ireland. It stretches from Blanchardstown (northeast of Dublin) to the Howth peninsula at the northwest into north county Dublin (Swords and Skerries).

There are two options for the origin of its name: the gealic meaning of white stranger, indicating the vikings who arrived in the Dark Middle Ages, or it may be related to Fingal Rónáin (= The kin-slaying of Rónán), but after reading the story I strongly doubt that.
