O'Mullan: What does the surname O'Mullan mean?

The last name O'Mullan is a common Irish surname and is typically found in the provinces of Connacht and Ulster in the west of Ireland.

Their name is often seen today in the U.S., especially in counties of New York, Massachusetts and Pennsylvania.

O'Mullan: Where does the name O'Mullan come from?

The last name O'Mullan is most commonly found in Ireland and areas of historic Irish migration, including the United Kingdom, Australia, New Zealand, and the United States.

The name originates from the Irish language word "Ó Maoláin," meaning grandchild of a devotee of St. John. During the 18th century, the anglicization of the name was written as Mullen or Mullane, and by the 19th century, the name changed to O'Mullan. The Irish people have a long history of emigration, with many O'Mullans leaving Ireland in the wake of the Great Famine in the mid-19th century.

In the United States, records show that O'Mullans began to arrive in New York, Massachusetts, Maryland, and Pennsylvania in the 1800s. Many of these immigrants went on to settle in other areas of the Midwest, particularly Pennsylvania and Nebraska. It's likely that a few O'Mullans traveled farther up the West Coast as well.

Today, the last name O'Mullan is still heavily concentrated in Ireland, England and Ireland's former colonies. Records show that in 2017, approximately 240 people in the United States had the last name O'Mullan, compared to over 22,000 in Ireland, and close to 11,000 in England and Wales. While many O'Mullans still retain the traditional spelling, many families have adopted more anglicized forms, such as Mullin or Mullen.
