The early 1900s brought a lot of immigrants to Hawaii from Korea, Japan, China, the Philippines, and Portugal to work on plantations. Sugar was king then.

My friend's great-great-grandfather came over from Portugal. His last name was Miento. Upon arriving at the docks, he must have been greeted by some asshole worker, because this worker listed his last name as "Mento." Mento in local Hawaii slang means crazy (or insane). His last name was Mento for several years until he left the plantation and moved to Honolulu. It was then changed back to Miento.
