Mahar
An Irish surname that is often treated as a spelling variant of Maher or Mäher-type names, though its exact origin is not always certain.
The #9,803 most common surname in the United States (2010 Census) — about 1 in every 93,503 Americans shares it.
Etymology
Mahar is most likely an anglicized Irish surname, often grouped with Maher and related spellings in older reference works. In many cases these names are connected with Irish forms that were reshaped in English spelling, rather than with a single transparent English word root. Because the historical spellings overlap and early sources list Mahar alongside Maher, Mahan, and Mahegan, the exact derivation can be hard to pin down with confidence from the surname form alone.
History
19th-century surname lists often group Mahar with other Irish names, suggesting it was understood as part of a broader Irish naming cluster. In the United States, Mahar has remained relatively uncommon but steady, and many bearers may descend from families whose surname spelling shifted between Mahar, Maher, and similar forms. The name is especially likely to be found in Irish-American contexts.
