Donegan

Donegan (), most commonly refers to a Gaelic Irish clan from Munster. The name is diminutive of ''Donn'' which means, "the Dark One", or in modern Irish, "brown", referring to hair colour. The most prominent dynasty were an Érainn people of the Múscraige and provided a King of Munster in the 10th century in the form of Flaithbertach mac Inmainén. Much later, the family provided the Dungan Baronets and two Earls of Limerick, the most notable of which Thomas Dongan, 2nd Earl of Limerick was a Governor of New York. Provided by Wikipedia
