10 Trends in Celebrity Baby Naming

The Reilly Factor

Last names can come first in the name game, as Angie Harmon and Jason Sehorn found with daughters Finley Faith and Avery Grace. Soledad O'Brien's other twin is named Jackson and NYPD Blue's Charlotte Ross found Maxwell arresting.

Who's Done It: Patricia Arquette heralded Harlow Jane and actress Thandie Newton picked the unusual Ripley.

The Latest Twist: Celtic names like Finnigan, Delaney, and Sullivan all sound cool riding in front and work for both sexes. Maybe that's why Holly Marie Combs (Piper from Charmed) also found Finley enchanting for her son.

Blast from the Past: Sean Penn named his son Hopper (after Dennis), and Lisa Marie Presley has daughter Riley.
