Finnegan
The story
Finnegan is the Finn family at its most Irish, descendant of Fionnagan, the fair one doubled into a diminutive, and it carries the best-read joke in the family: an Irish wake, a novel nobody finishes, and a surname that grins about both. The living family around it is storied here in force: Finn, the anchor, about 35,400; Finley, the crossover, about 42,200. Finnegan's own record is young: about 80 in the 1990s, 2,200 in the 2000s, 6,700 in the 2010s, and 4,100 so far this decade, closing on the full 2010s with years to run. It goes to boys about 13,000 to 100, and Finn waits inside it for every one of them. Fair at the root, literary at the edges, and a record climbing with years to run: the wake was premature.
