Welsh Names that Start With O

Owen, a resonant Celtic name, has ranked among the Top 100 boys' names in the US for 20 years and is now at its highest point ever.

Olwen is a Welsh favorite, the name of a legendary princess in what is believed to have been the earliest Arthurian romance, and in fact one of the first recorded examples of Welsh prose.

Ever since singer Michelle Branch gave it to her daughter in 2005, Owen has started to be used for a small number of girls each year as well. Just 39 baby girls received the name in 2021, compared with over 8700 boys.

Olwyn is a popular Welsh name that might be an alternative to the more familiar Bronwen or Rhonwen -- though in Wales the female form is usually spelled -wen and the male one -wyn.
