as related to me over dinner some time in the past few days, and I believe it's attached to one of the Flickr pictures that's tagged "youghal": two american tourists enquired of a local, "how do you pronounce the name of this city?" The local responded, "it's a town, actually". The tourists enquired, "sorry, how do you pronounce the name of this town?" The local replied, "it's not much of a town, either".
The answer they sought - and eventually received - is "Yawl". The "gh" isn't an Irish artifact, either - the Irish name is "Eochaill" (possibly with an acute accent on the o) which means "Yew Forest".Part of the other side of the river, where I grew up, is called "Ard Sailleach" or "Tall Sallies". Not Little Richard's ones, but rather yet more yew trees. Apparently they used be pretty common in those parts.
