Rideout
A surname most likely built from a nickname or phrase referring to riding out, though older writers also speculated about a fortification or place-name origin.
The #8,313 most common surname in the United States (2010 Census) — about 1 in every 77,457 Americans shares it.
Etymology
The surname is usually treated as English and probably began as a nickname or descriptive byname, with the elements suggesting something like “ride out” or “riding out.” Older authorities also proposed other explanations, including a link with a redoubt or fortified place, but that derivation is uncertain and was not generally accepted. Historical spellings such as Ridout and Ridoutt point to the same name-family.
History
The name appears in several spelling forms in British records, including Ridout and Ridoutt, and later also turned up in America. Nineteenth-century surname writers debated whether it came from a place, a fortification, or a descriptive phrase, and modern treatment usually keeps the origin cautious. The name remains relatively uncommon in the United States.
