When I studdied at Oxford I was able to trace the human who may have been the source from which the Arthur legend was derrived. Ãedán mac Gabráin was an Irish War Lord / King whoes basic story kinda-sorta-maybe follows the legend but Serrendipity is right, the legend as we know it today was invented by a lot of good authors like Geoffrey of Monmouth (1130ish) and Sir Thomas Malory (late 1400s).
Merlin is mentioned in Geoffrey of Monmouth's Historia Regum Britanniae but he was a combination of a few people from different centuries: Ambrosius Aurelianus, Lailoken, Merlynum, and Myrddin Emrys. It was Geoffrey who named him Merlini.
