Rileys

Rileys, most commonly encountered, is a surname of Irish origin. It is an anglicized form of the Gaelic surname Ó Raghallaigh, meaning "descendant of Raghallach." Raghallach itself is a personal name meaning "valiant" or "brave ruler."

The surname Rileys (and its variants such as Riley and Reilly) is prevalent in Ireland, particularly in County Cavan, where the Ó Raghallaigh clan historically held power as chieftains. Emigration from Ireland, particularly during the Great Famine in the 19th century, led to the widespread distribution of the surname in countries such as the United States, Canada, Australia, and the United Kingdom.

Beyond its primary use as a surname, "Rileys" may also refer to a family or group of people bearing the Riley surname. The plural form could also be used in the possessive sense, such as "Rileys' house," indicating a house belonging to a family named Riley. Furthermore, it could potentially be used as a brand name, though this usage would be less common and would depend on context.
