This was used for the name 'Rowena', who was the sister of either Hengist or Horsa, the Saxon mercenary leaders whom Vortigern invited to Britain. Wanting to marry her, Vortigern asked them what they wanted in exchange for her. They wanted Kent, and they got it, thus beginning the Anglo-Saxon wars against the British.
I had a friend in high school named something similar: Rhianwen. She pronounced it ree-ON-wen.

I think this is quite a nice name, but very Welsh-sounding, and I think unless you live in Wales or a Welsh-speaking community, this name might sound quite strange, but nevertheless, a nice name. And I had also heard that this name was the Welsh variant of Rowena. :)
