This individual has no known canonical name.  While the information presented is canonical, the individual described lacks an official name, thus the title is conjecture.

He was an Alteran who lived during the split into two factions of his race. He was seen at the decision about the Ark Of Truth, and was among the Alterans present when they decided to leave their home planet for the Milky Way. It can reasonably be inferred that he was one of the Alterans who fled to the Milky Way. ("Stargate: The Ark of Truth")
