Where did the Irish Mangan family come from? What is the Irish Mangan family crest and coat of arms? When did the Mangan family first arrive in the United States? Where did the various branches of the family go? What is the Mangan family history?

All Irish surnames have a unique and often romantic meaning. The name Mangan originally appeared in Gaelic as O Mongain, which is derived from the word mongach, which means hairy.


Scribes and church officials, lacking today's standardized spelling rules, recorded names by how they were pronounced. This imprecise guide often led to the misleading result of one person's name being recorded under several different spellings. Numerous spelling variations of the surname Mangan are preserved in documents of the family history. The various spellings of the name that were found include O' Mongain (Gaelic), Mangan, Mongan, Mongin, Mungan, Mungen, Mongun, O'Mongan, O'Mongin, O'Mungen, O'Mongun, O'Mongun, O'Mangan and many more.

First found in Connacht (Irish: Connachta, (land of the) descendants of Conn), where they held a family seat and styled as one of the Irish Clanns who were descendants of King Niall of the Nine Hostages. They were descended through Eochy Moyvane, to Niall Mor, his son, the great Niall of the Nine Hostages. Descended was O'Mongain the great chief of the Mangans whose territories included branches in Mayo, Connacht, Cork and Limerick.

Ireland saw an enormous decrease in its population in the 19th century due to immigration and death. This pattern of immigration began slowly in the late 18th century and gradually grew throughout the early portion of the 19th century. However, a dramatic increase in the country's immigration numbers occurred when the Great Potato Famine struck in the 1840s. The early immigrants to North America were primarily destined to be farmers tending to their own plot of land, those that came later initially settled within pre-established urban centers. These urban immigrants provided the cheap labor that the fast developing United States and soon to be Canada required. Regardless of their new lifestyle in North America, the Irish immigrants to the United States and Canada made invaluable contributions to their newly adopted societies. An investigation of immigrant and passenger lists revealed many Mangans:
