Galvan
A surname with several possible roots, including an Irish form of O'Gáibhin/Gallivan and a likely Spanish occupational link to a tax collector or levy man.
The #630 most common surname in the United States (2010 Census) — about 1 in every 5,736 Americans shares it.
Etymology
The surname Galvan is probably not single-origin. In Irish records it appears as a variant connected with O'Gáibhin, later Anglicized in forms such as Gallivan, Galvin, and Galven. In Spanish, older scholarship also links Galván to a medieval fiscal term related to a collector of dues or taxes, so the name may have developed independently in different language areas. Because the historical sources point to more than one explanation, the safest answer is that Galvan has multiple possible etymologies rather than one certain root.
History
In Ireland, this name is found among surnames grouped with Galvin and related forms, especially in Munster. In Spanish-speaking areas, Galván is a long-established surname and may reflect a separate occupational origin. The modern U.S. spelling Galvan can therefore reflect either Irish-American or Hispanic ancestry, depending on the family line.
