Lawler
An Irish surname that is often treated as a spelling variant of Lalor/Lawlor, with roots in an older Gaelic family name.
The #2,516 most common surname in the United States (2010 Census) — about 1 in every 21,460 Americans shares it.
Etymology
Lawler is generally explained as an Anglicized form closely related to the Irish surname Lalor/Lawlor. Nineteenth- and early-twentieth-century surname writers commonly grouped Lawler with these forms rather than treating it as fully separate. The deeper Gaelic source is usually traced to an older Irish family name, though the exact original spelling and meaning are not always stated consistently in the older sources.
History
In Irish records and later diaspora usage, Lawler appears alongside Lalor and Lawlor, and the forms often overlap in spelling and pronunciation. The name is found in Ireland and became more widely visible in English-speaking countries through migration. Historical statistical works from Ireland show Lawler as a recognized but less common form than Lawlor or Lalor.
