Today's Irish surnames are underpinned by a multitude of rich histories. The name O'Mulen 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 O'Mulen family

The surname O'Mulen 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.

Migration of the O'Mulen family

Ireland became inhospitable for many native Irish families in the 19th centuries. Poverty, lack of opportunities, high rents, and discrimination forced thousands to leave the island for North America. The largest exodus of Irish settlers occurred with the Great Potato Famine of the late 1840s. For these immigrants the journey to British North America and the United States was long and dangerous and many did not live to see the shores of those new lands. Those who did make it were essential to the development of what would become two of the wealthiest and most powerful nations of the world. These Irish immigrants were not only important for peopling the new settlements and cities, they also provided the manpower needed for the many industrial and agricultural projects so essential to these growing nations. Immigration and passenger lists have documented the arrival of various people bearing the name O'Mulen to North America: D. B. Mullen settled in Philadelphia with his wife, son and servants, in 1807; Daniel, Bernard, Charles, Edward, Hugh,James, John, Margaret, Michael, Patrick, Peter, Thomas and William Mullen all arrived in Philadelphia between 1840 and 1860.
