The surname Mangant was 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.

Mangant Spelling Variations

The spelling of names in Ireland during the Middle Ages was rarely consistent. This inconsistency was due to the scribes and church officials' attempts to record orally defined names in writing. The common practice of recording names as they sounded resulted in spelling variations such as Ó Mongain (Gaelic), Mangan, Mongan, Mongin, Mungan, Mungen, Mongun, O'Mongan, O'Mongin, O'Mungen, O'Mongun, O'Mongun, O'Mangan and many more.

Migration of the Mangant family

Many destitute Irish families in the 18th and 19th centuries decided to leave their homeland, which had in many ways been scarred by English colonial rule. One of the most frequent destinations for these families was North America where it was possible for an Irish family to own their own parcel of land. Many of the early settlers did find land awaiting them in British North America, or even later in America, but for the majority of immigrants that arrived as a result of the Great Potato Famine of the late 1840s the ownership of land was often a long way off. These Irish people were initially put to work on such industrial projects as the building of bridges, canals, and railroads, or they worked at manufacturing positions within factories. Whenever they arrived, the Irish made enormous contributions to the infant nations of Canada and the United States. Some of the earliest immigrants to bearer the name of Mangant were found through extensive research of immigration and passenger lists: John, Mary and Judy Mangan who arrived in New York State in 1853; Francis, Henry, James, John, Michael, Patrick, Thomas, and William Mangan, all arrived in Philadelphia, Pennsylvania between 1826 and 1868.
