Gwyndolyn, derived from Welsh elements 'gwyn' meaning white or fair, and 'dolen' referring to a whirlpool, is an uncommon yet enchanting feminine given name. It first appeared in literature as the middle name of Gwendolyn, a character in Sir Walter Scott's novel 'The Bride of Lammermoor'. The unique spelling of Gwyndolyn offers a distinct touch, setting it apart from more common variants such as Gwendolen or Gwendoline.
The name Gwyndolyn seems to have had its heyday in the mid-20th century, with peaks in popularity around the late 40s and early 50s, reaching a high of 16 births in 1952. However, it has since declined significantly, with only 5 or fewer births per year from the 1970s onwards, and even a few years with no recorded births at all (e.g., 1942, 1973). The total number of births recorded over this period is 500.
