is an Irish surname
that arose simultaneously in a number of areas, including Cork
. The best known family of the name had its territory near the modern town of Fermoy
in north Cork, and were originally the ruling family of the Fir Maighe
tribal group which gave its name to the town. They claimed descent from Mug Ruith
, the legendary magician of the Fir Bolg
. They ceded pre-eminence to the O'Keeffe
family in the eleventh century, but remained powerful in the area. Along with the other Fir Maighe families they lost their power when the Normans
conquered the territory in the twelfth and thirteenth centuries.
The Coat of Arms are azure with a crescent argent between nine stars of eight points. The motto, Virtve et Valore ("By Virtue and Valor") is derived from Old English rather than from the Irish translation of Ó Dubhagáin, meaning "dark" or "black." The motto is derived from the Old English word dūgan (preterite-present: dēag ‘it is useful’, dugon ‘they are useful’, dohte ‘it was useful’). Other definitions include "to avail, to be of use, to serve"; Ðonne his ellea deah ("when his valour avails"); "to be fit or strong".
In modern day, the name is found throughout Ireland. In the north, Dugan, Dougan, and Doogan are common, a large portion descended from families originally in County Fermanagh. Doogan is common in County Donegal. Duggan is most prevalent in Dublin, Munster, and the majority of County Cork, County Tipperary, County Wexford, and County Waterford.
Dugan and Dougan are also common Scottish names. Throughout other English speaking countries, Dugan and its many variants, including Duggan, Dougan, Doughan, Doogan, and Duggin are widespread. Dugan ranked 1,705 in surname listings in the 1990 United States Census. In Great Britain, Duggan ranked 1,950 in surname listings from the 1881 Census, then surged to 1,025 in surname listings from the 1996 Electoral roll.
