Morfin
A surname with likely Spanish roots, probably developed from a personal name or local name rather than an English word surname.
The #7,391 most common surname in the United States (2010 Census) — about 1 in every 68,534 Americans shares it.
Etymology
Morfin is most likely a Hispanic surname, but its exact origin is not fully settled from general surname evidence alone. It may be related to a regional or shortened form of an older personal name or place name, rather than having a transparent modern meaning in Spanish. Because the form is uncommon, it is best treated cautiously as a surname of uncertain specific derivation within the Spanish-speaking naming tradition.
History
The surname is found chiefly in the United States today, especially among families of Hispanic background. Its present distribution fits a surname brought through migration from Spanish-speaking regions, but there is not enough standard onomastic evidence to tie it securely to one exact original locality or root. In genealogy work, it often appears alongside spellings and records that may vary slightly over time.

Fun fact
