Deiham History, Family Crest & Coats of Arms
- Origins Available:
The ancient Gaelic form of the Irish name Deiham 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 Deiham family
The surname Deiham 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.

Migration of the Deiham family
Many Irish families did not fare so well within the English-ruled Ireland. Besides racial and religious discrimination, many families were renting out small tracts of farmland from absentee landowners at often unreasonable rates. Beginning in the late 18th century, moderately well off Irish families decided to emigrate to British North America or the United States in order to own their own plot of land. A radical change occurred in the 1840s, however, with the Great Potato Famine of the 1840s. Up to this point, the island's population had been increasing rapidly and a steady demand over the years for grain crops had depleted soil. Two failed crops and one poor one caused widespread disease and starvation. Thousands boarded ships looking for opportunities elsewhere. North America welcomed them as a source of cheap labor required for the many industrial and infrastructure projects underway, and as a means to quickly occupy the western regions. Research into immigration and passenger ship lists indicates that people bearing the name Deiham were among the earliest settlers to arrive in North America: 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.
