Marcano
A Romance-language surname that likely began as a patronymic or family-name form built from the personal name Marco/Marcos.
The #7,789 most common surname in the United States (2010 Census) — about 1 in every 72,544 Americans shares it.
Etymology
Marcano is most likely a surname formed from the given name Marco, the Romance form of Latin Marcus. In Spanish and related naming traditions, surnames built from a personal name often marked descent, affiliation, or family association. The ending -ano can also appear in surnames as a regional or adjectival-looking suffix, but in this case the clearest explanation is a family-name form connected with Marco/Marcos.
History
The surname is found especially in Spanish-speaking communities, including the Caribbean and Latin America, and it also appears among diaspora families in the United States. Like many surnames based on a common given name, it probably arose independently in more than one place. Modern bearers may therefore not all share a single recent ancestor.

Fun fact
Because Marco was such a common medieval and early modern given name, surnames derived from it could develop in several separate families without any direct connection between them.
