"When I taught at Princeton five years ago, I asked my old college roommate to get to John Conway and ask. To my surprise it took 3, not 2, degrees of separation to get to him. He said he wanted the name to end in "-day" and "Dooms" popped into his head."
Likely that sprung to mind because of the "Domesday Book":
"Domesday Book (/ˈduːmzdeɪ/ DOOMZ-day; the Middle English spelling of "Doomsday Book") is a manuscript record of the Great Survey of much of England and parts of Wales completed in 1086 at the behest of King William the Conqueror."
