Meaning and history
Iona comes from the Scottish island where Saint Columba founded an influential monastery in the sixth century. The island's name is probably from the Old Norse word ey, meaning "island." Its religious and geographical importance led to its use as a personal name. Notable bearers include British musician Iona Brown and artist Iona Rozeal Brown.
Iona moved from #845 to #849 for girls between 1945 and 1946. Its highest annual birth count came in 1918, with 404 births.
