The 10 Most Popular Male Welsh Names (and Their Pronunciation)

The ebb and flow of name popularity is a dynamic phenomenon. Names that once dominated the charts a decade ago can fade into obscurity in the next, just like my own name, Heather. Frequently, names stage a comeback after years of being dormant, illustrating the cyclical nature of naming trends influenced by societal shifts and cultural currents. Take vintage names from the early 20th century, for example—they’re currently enjoying a renaissance in popularity!

Today, we’ll delve into the 10 most popular Welsh names for boys and men. These selections are derived from the latest data (2021) provided by the Office for National Statistics in England and Wales. Each name is accompanied by an audio file with the correct Welsh pronunciation. Perhaps you’ll find inspiration among these names when the moment arrives to choose the perfect one for your little bundle of joy!
