Vortigern, Your post was incrediable! I was just participating in an Arthurian quiz at another site and wanted to reread your post as a reference.
The Question was:
"Who was Merlin supposedly the illegitimate child of?"

Diantha Livius' info on Merlin was good, and in addition I would like to add a few tidbits I picked up from: Britannia;historical biographies

Merlin was the illegitimate son of a monastic Royal Princess of Dyfed. The lady's father, however, King Meurig ap Maredydd ap Rhain, is not found in the traditional pedigrees of this kingdom and was probably a sub-King of the region bordering on Ceredigion. Merlin's father, it is said, was an angel who had visited the Royal nun and left her with child. Merlin's enemies claimed his father was really an incubus, an evil spirit that has intercourse with sleeping women. The evil child was supposed to provide a counterweight to the good influence of Jesus Christ on earth. Merlin, fortunately, was baptized early on in his life, an event which is said to have negated the evil in his nature, but left his powers intact. The original story was presumably invented to save his mother from the scandal which would have occurred had her liaison with one Morfyn Frych (the Freckled), a minor Prince of the House of Coel, been made public knowledge.

This was very interesting little tidbits, so I thought I would share with the rest of Y'all.
