Meaning and history
Shannon is a name derived from the River Shannon, Ireland’s longest river, known in Irish as an tSionainn. It is linked to the legendary figure Sionann and is sometimes said to have been named after her, though it is more likely that she was named for the river, whose name may be related to Old Irish sen meaning “old” or “ancient.” As a given name, Shannon began to become common in America after the 1940s.
Shannon moved from #825 to #917 for girls between 2012 and 2013. Its highest annual birth count came in 1970, with 13,547 births.
