Michael Norris wrote: The Mighty Mongol was from Calgary and I believe his real name was Edward Sullivan. He had a short run in Florida in the early 70s as Jim Slade, brother and partner to Blackjack Slade. Worked as the Mighty Mongol in Tri States (McGuirk) and the Gulf Coast in 1973. He held the GC Heavyweight title and the United States tag title (with Juan Sebastien who was working as The Rugged Russian) in the Gulf Coast area in 1973. He worked as Ed Sullivan in Calgary.
