Throughout history, very few Irish surnames have exclusively maintained their original forms. Before being translated into English, Hennagyn appeared as Ó Dubhain, where the name means a "dark complexioned man." 1

Early Origins of the Hennagyn family

The surname Hennagyn was first found in County Clare, County Limerick and Sligo (Irish: Sligeach), in the province of Connacht in Northwestern Ireland. Some of the County Clare families were thought to have been regionally in County Cork. 2

Migration of the Hennagyn family

To escape the religious and political discrimination they experienced primarily at the hands of the English, thousands of Irish left their homeland in the 19th century. These migrants typically settled in communities throughout the East Coast of North America, but also joined the wagon trains moving out to the Midwest. Ironically, when the American War of Independence began, many Irish settlers took the side of England, and at the war's conclusion moved north to Canada. These United Empire Loyalists, were granted land along the St. Lawrence River and the Niagara Peninsula. Other Irish immigrants settled in Newfoundland, the Ottawa Valley, New Brunswick and Nova Scotia. The greatest influx of Irish immigrants, however, came to North America during the Great Potato Famine of the late 1840s. Thousands left Ireland at this time for North America and Australia. Many of those numbers, however, did not live through the long sea passage. These Irish settlers to North America were immediately put to work building railroads, coal mines, bridges, and canals. Irish settlers made an inestimable contribution to the building of the New World. Early North American immigration records have revealed a number of people bearing the Irish name Hennagyn or a variant listed above, including: Jane Downe who settled in Jamaica in 1685; John Downe settled in Barbados in 1685; another John Downe settled in Virginia in 1670; Robert Downe settled in St. Christopher in 1635.
