In 1898, a London newspaper wrote a bunch of articles about a gang known as “Hooley’s Gang”, they would call themselves Hooligans. Strangely, the word appeared in San Francisco and New York at the same time. But no one ever named Hooley was found, it was presumed that Hooley was an Irish reference for Rowdy, Wild.
Other sources claim the word originated from another criminal named Patrick Hoolihan. He was a bouncer and a thief in London, borough of Southwark. Few other theories claim that it was an Irish family in the borough of Southwark, they were known as the Hoolihans and were very wild. And the other other theories suggest just that the word houlie, Irish, is the meaning of wild and hooligan comes from that.
