Hearne
An English and Irish surname that can be either a spelling of Hearn or an anglicized form of Irish Ahern/Aherne.
The #9,177 most common surname in the United States (2010 Census) — about 1 in every 86,873 Americans shares it.
Etymology
The surname Hearne is best understood as a spelling variant of Hearn in English records, but it also appears as an anglicized form of Irish surnames such as Ó hEachthigheirn / Ahern-type names in older Irish scholarship. The English side may come from a nickname or personal-name source, while the Irish side is tied to a Gaelic family name that was often rendered in several similar spellings. Because the historical sources mix several related forms, Hearne is not a single-origin surname in every case.
History
Historical surname dictionaries commonly treat Hearne, Hearn, Ahern, and Hene/Herne-like forms as overlapping spellings in records, especially in Ireland and England. In Irish contexts, Hearne is often grouped with Ahern/Aherne as an anglicized Gaelic name; in English contexts it can simply be a spelling variant that became fixed in some families. The result is a surname with more than one pathway into modern use.

Fun fact
19th-century surname books often cross-reference Hearne with both English and Irish forms, which is why the same spelling can have different family histories.
