Show ContentsMollen History, Family Crest & Coats of Arms

Today's Irish surnames are underpinned by a multitude of rich histories. The name Mollen originally appeared in Gaelic as either Ó Meallain, Ó Maolain or Mac Maolain. The first surname is derived from the word meall, which means pleasant. The second and third surnames are derived from maol, which means bald.

Early Origins of the Mollen family

The surname Mollen was first found in the province of Connacht (Irish: Connachta, (land of the) descendants of Conn) where the Mullen, Mullin and Mullan spellings were popular. They were descended from the Kings of Connacht and are of the same basic stock as the O'Concannons. Branches were also found in Cork, Limerick, and Clare where the Mullane and Mullins spellings were the most frequent. Some were found north in Ulster and Tyrone and Derry. 1 This latter group is difficult to trace as the Scottish MacMullen or McMullen settled there during Cromwell's Plantation of Ulster.

United States Mollen migration to the United States +

The 19th century saw a great wave of Irish families leaving Ireland for the distant shores of North America and Australia. These families often left their homeland hungry, penniless, and destitute due to the policies of England. Those Irish immigrants that survived the long sea passage initially settled on the eastern seaboard of the continent. Some, however, moved north to a then infant Canada as United Empire Loyalists after ironically serving with the English in the American War of Independence. Others that remained in America later joined the westward migration in search of land. The greatest influx of Irish immigrants, though, came to North America during the Great Potato Famine of the late 1840s. Thousands left Ireland at this time for North America, and those who arrived were immediately put to work building railroads, coal mines, bridges, and canals. In fact, the foundations of today's powerful nations of the United States and Canada were to a larger degree built by the Irish. Archival documents indicate that members of the Mollen family relocated to North American shores quite early:
