Some time ago I came across the name Adenydd whilst browsing other name sites, and it became another one of those odd names which struck my fancy. Other name websites tell me that this is a feminine Welsh name meaning "winged". As always, however, I doubted the accuracy of these sources since I was unable to find information on Adenydd on any Welsh-specific databases. Through consulting the Welsh-English dictionary at http://www.geiriadur.net
, I was able to determine that "aden" does mean "wing" in Welsh. The entry also noted "n.f. (adenydd)" -- so adenydd is marked as a feminine noun. "Winged" did not yield any results close to adenydd (winged = adeiniog, asgellog). So from this research I was able to conclude that adenydd is probably not "winged" but merely "wing".
Now to the name Adenydd. Searching online, I was unable to find any instance of Adenydd being used as a real person's name with 100% certainty. I did find two Adenydds via Facebook, but I can't know for certain whether these are real names or online monikers. I got plenty of fictional character, screen names and references to the Welsh word. Yet I couldn't find historical usages or full names of real people.
So I ask anyone with the knowledge -- is Adenydd a legitimate Welsh name that has been used (and can be used)?
