Mulvaney
An Irish surname, most likely an Anglicized form of a Gaelic family name beginning with Mul- or Maol-, though its exact root is not certain.
The #9,821 most common surname in the United States (2010 Census) — about 1 in every 93,673 Americans shares it.
Etymology
Mulvaney is generally treated as an Irish surname of Gaelic origin. The initial element Mul- usually reflects Gaelic maol, meaning "bald," "tonsured," or by extension "follower/devotee" in older Irish names. The second element is less secure in this case, and 19th-century sources often grouped Mulvaney with other Irish Mul- surnames rather than offering a firm derivation.
History
The name is found among Irish surnames that were heavily Anglicized in the 19th century. Historical surname lists place Mulvaney alongside forms such as Mulvay and Mulry, which suggests a shared Irish naming pattern rather than a single clear English source. In modern use it remains most strongly associated with Ireland and Irish diaspora communities, especially in the United States.
