[Facts] Re: Pronounciation of Eiluned?
The "u" in Welsh is pronounced "ee". I'm afraid, therefore, that I must disagree with the other poster.
Eye-lee-ned would be the correct pronounciation. For some reason, however, most bearers of that name soften the "u" sound and tend to pronounce it "Eye - lyn - ed" or even "El - lyn -ed".
