Shannon

Shannon is derived from the River Shannon, the longest river in Ireland. The river’s Irish name, Sionainn, is associated in legend with Sionann, a woman who drowned in the river after seeking wisdom from a sacred well. The etymology of Sionainn is uncertain, but it is sometimes interpreted as ‘wise river’ or ‘possessor of wisdom.’ As a given name, Shannon began to be used in the English-speaking world in the twentieth century for both girls and boys.
