Mancia
A surname with likely Italian or Spanish roots, probably from a place name or a nickname based on a related word form.
The #8,106 most common surname in the United States (2010 Census) — about 1 in every 75,506 Americans shares it.
Etymology
Mancia is best treated as a surname of uncertain origin, though it is most likely from Italian or Spanish naming patterns. It may derive from a place name, a local surname form, or a nickname built from a Romance word now obscured by regional spelling. In some cases, surnames like this preserve older dialect forms rather than a single obvious standard word.
History
The name is relatively uncommon in the United States and is most likely associated with immigrant families from Italy or the Spanish-speaking world. Because the surname is not strongly standardized in the historical onomastic record, its exact origin can vary by family line and region. In genealogical use, it is worth checking for local records and variant spellings in southern Italy, Sicily, Spain, and Latin America.

Fun fact
