Meaning & origin

Garreth is a rare variant spelling of Gareth, a name brought to prominence by Sir Thomas Malory's 15th-century Arthurian work Le Morte d'Arthur, where Gareth was a Knight of the Round Table. In U.S. records, Garreth first appeared in 1940 and reached its peak popularity in 1998, though it has never been a common choice. The name has remained stable in usage, appealing to parents seeking a traditional Welsh name with a slightly unique spelling. Despite its obscurity in top state rankings, Garreth carries a literary and chivalric resonance that connects it to a rich cultural heritage.

Garreth is generally considered a variant spelling of Gareth, a name of Welsh origin popularized by Arthurian legend. The etymology of Gareth is debated; it may derive from the Welsh word 'gwaredd' meaning 'gentleness' or from 'Gwalchmai', a name of uncertain meaning. The spelling Garreth emerged as an anglicized form, particularly in the 20th century.
