Dear Jackie: I searched for your "GuÞlac" using "th" instead of the "Þ", and found a whole long list of lovely sites about him and his sister Pega. I am indeed grateful to you for giving me a clue that will yield many pleasant hours of browsing.Just in case anyone else is interested, here is the URL:

P.S. Interestingly, the manuscripts spell his name with "th" not with a "Þ".
