O'Mullan History, Family Crest & Coats of Arms
Today's Irish surnames are underpinned by a multitude of rich histories. The name O'Mullan originally appeared in Gaelic as either O Meallain, O 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'Mullan family
The surname O'Mullan 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.  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'Mullan family
Death and immigration greatly reduced Ireland's population in the 19th century. For the native Irish people poverty, hunger, and racial prejudice was common. Therefore, thousands left their homeland to seek opportunity in North America. Those who survived the journey and the quarantine camps to which they arrived, were instrumental towards building the strong developing nations of the United States and the future Canada. By far, the largest influx of Irish settlers occurred with Great Potato Famine during the late 1840s. These were employed as construction or factory workers. An examination of passenger and immigration lists has shown early immigrants bearing the name O'Mullan: 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.
