Finnegan
If you like the Finn names and love James Joyce, Finnegan is extremely winning. "Will & Grace" 's Eric McCormack chose the Finnigan spelling for his son. And of course Finnegan gains you access to the great short form Finn.
James Joyce took the title of Finnegan's Wake from an old Dublin ballad.
Finnegan represents a whole genre of Irish family names you might consider, such as Harrigan, Brannigan, Corrigan, Donegan, Mulligan, Flanagan, Lanigan, and more.
