Matherne
A surname of likely French origin, probably a regional or altered form related to a place-name or personal-name tradition.
The #9,451 most common surname in the United States (2010 Census) — about 1 in every 89,699 Americans shares it.
Etymology
Matherne is most likely a surname that entered English through French, especially in forms found in Louisiana and other French-speaking or French-influenced communities. Its exact root is uncertain: it may be a regional or altered spelling from a French surname or place-name built from older local elements, rather than a transparent word with an obvious modern meaning. Because the form is not common in standard surname dictionaries, the safest explanation is that it reflects a French family name that became fixed in a local spelling tradition.
History
The surname is best known in the United States, especially in Louisiana, where many French-origin family names were preserved and reshaped in spelling over time. The modern distribution suggests a small, regionally concentrated surname that likely reflects Acadian, Creole, or other French-descended settlement patterns. Because the name is relatively rare and not securely explained by the major standard onomastic references, its detailed history remains somewhat uncertain.
