Douhan History, Family Crest & Coats of Arms
- Origins Available:
The ancient Gaelic form of the Irish name Douhan was O Dubhaigan. The first portion of the name is the word dubh, which means black; the second portion is likely some obsolete Irish personal name.
Early Origins of the Douhan family
The surname Douhan was first found in County Clare (Irish: An Clár) located on the west coast of Ireland in the province of Munster, where O'DuilAgin, O'Dugan, (or O'Deegan), chief of Muintir ConIochta, a district in the parish of Tomgraney, in the barony of Tullagh.
The family line is directly traceable to Fergus Mor (Fergus the Great). In turn his ancestry is associated with King Ir, brother of the equally famous Heremon. The name was first found near what is now the town of Fermoy, in the territory formerly known as Roche's Country. This territory encompassed the junction of the counties Cork, Tipperary and Waterford. In modern times, the surname is generally found in these three counties.
However, there was another O'Dugan sept in the territory called Ui Maine, also called Hy Many, which spans eastern county Galway and southern county Roscommon. This sept gave their name to the place called Ballyduggan, near Loughrea.

Douhan Spelling Variations

This led to the problem of one name being recorded under several different variations and thus resembling more than one person. Among the many spelling variations of the surname Douhan that are preserved in archival documents of this era include Dugan, Duggan, O'Duggan, Dougan, Douggan, Dewgan, Deugan and many more.

Migration of the Douhan family
Irish emigration to North America began modestly in the late 18th century. At this time, Irish families made the journey to British North America and the United States by choice and after careful consideration: they were primarily in search of a suitably large stretch of land to call their own. This pattern would change most dramatically during the Great Potato Famine of the late 1840s. For example, the years 1825-1845 saw approximately 450,000 heading to British North America and 400,000 to the United States, but in 1847, at the height of the famine, it is estimated that more than 104,000 Irish immigrants went to British North America and more than 119,000 to the United States. An examination of passenger and immigration lists has revealed many early immigrants bearing the name Douhan: James Dugan who settled in New York State in 1775; John Duggen, who arrived in Maryland in 1739; Cornelius Duggin, who arrived in Albany, NY in 1762; John Duggin, who came to Boston in 1765.
