The ancient Gaelic form of the Irish name Deehane 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 Deehane family
The surname Deehane 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
. 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.

of the name, including Dugan, Duggan, O'Duggan, Dougan, Douggan, Dewgan, Deugan and many more.

Migration of the Deehane family to the New World and Oceana
In the 18th and 19th centuries, hundreds of thousands of Irish immigrants landed on North American shores. Although many of them were merely looking for a free plot of land and living of their very own, many later immigrants were desperately fleeing an overcrowded land that did not have sufficient food for its inhabitants. The exodus from Ireland
was greatest during the 1840s when the Great Potato Famine
had stricken the island. Although this large influx of Irish was unpopular with the great majority of people already established within the major centers, these Irish were critical to the speedy development of the United States and those colonies that would eventually become known as Canada. These immigrants provided the cheap labor required to build modern roads, bridges, canals, and railways. Research of passenger and immigration lists has shown a number of immigrants to North America baring the name of Deehane: 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.
