Meaning & origin

Glyn is a Welsh name meaning 'valley' or 'glen', drawn directly from the Welsh word for a geographical feature. In the United States, Glyn first appeared in birth records in 1912 but never achieved widespread popularity. Its peak year was 1934, during the heyday of Welsh and Celtic revival names. The name's trajectory has been stable, with a consistent but very low level of use over the decades. In the 1930s, Glyn was most common, though it never ranked among the top names. The name has not appeared in any state's top baby name lists, reflecting its niche appeal. Parents today might choose Glyn for its simple, nature-inspired meaning and strong Welsh heritage.

Glyn derives from the Welsh word 'glyn' meaning 'valley' or 'glen'. It is a toponymic name that originated as a short form of Welsh names beginning with Glyndwr or Glynys, and later became used independently. The name has remained in steady but modest use in Wales and among Welsh communities, peaking in the 1930s.
