hooligan

The word traces back through Proto-Celtic and Old Irish to a name meaning descendant, which eventually produced the Irish surname Ó hUallacháin, anglicized as Houlihan. 'Hooligan' is probably a variant of that surname, first appearing in the 1890s.

What began as a personal surname became, by the 1890s, a general English word for an unruly troublemaker, with no other documented shifts in meaning.

It shares its root with the Irish surname Houlihan, from which it's probably derived.
