However, you could consider these options:
* "Ffawydd": This word means "hazel" in Welsh and refers to the tree itself. You could use it as a nature-inspired name, similar to how "Willow" is used in English.
* "Elowen": This name means "elm tree" in Welsh and has a similar sound and feel to "Hazel."
* "Gwenllian": This name means "white hazel" and is a more traditional Welsh name. It's a beautiful option if you're looking for a strong and elegant name.
Ultimately, the best way to choose a Welsh name for "Hazel" depends on your personal preferences and the significance you want the name to have.
