Shannon is a Gaelic name that shares its sound with Ireland’s greatest river.
Where does the Shannon name come from?
Shannon is generally an anglicised form of the Gaelic Ó Seanáin, “descendant of Seanán” — a personal name based on sean, “old” or “wise,” in effect “little wise one,” a name borne by several early saints. Though it echoes the River Shannon, the surname comes from this personal name rather than the river itself.
