Glyn is an attractive and unique given name of Welsh origin, derived from the word "glyn," which translates to "valley" or "glen." This name has a rich history tied to Wales' geography and culture. It gained prominence in the 19th century due to its association with notable figures like Glyn Hughes, a prominent British politician during that era. The name Glyn is also connected to Glyn Cywarch, a prominent mountain range in northern Wales, further reinforcing its connection to Welsh landscapes. Despite being primarily used as a boy's name, Glyn has been known to be used for girls as well, adding versatility and flexibility to its usage.
The name Glyn experienced a significant rise and fall in popularity over the years, with peaks in the late 1920s to early 1930s and again in the mid-1940s to early 1950s, followed by a steady decline from the late 1950s onwards. The highest number of births was recorded in 1964 with 21 births. However, after 1973, there were only a handful of Glyn births each year, with several years recording less than 10 births.
