> A Chairde,
> I'm looking for some help regarding a Celtic legend I read some time ago,
> but I'm having trouble re-locating it.
> The story tells of how Saint Patrick visited (I think) a noble family. He
> told the two daughters about Jesus Christ and they wanted to meet him. He
> told the daughters that they could not meet him because he was in Heaven.
> They became very sad, but at that moment, they died and their souls rose to
> Heaven to meet Jesus.
> What I'm looking for is the name of this legend, and the names of the
> daughters. I tried researching in my local library but I can't seem to find
> it anywhere. Is there an online version of this story available?
