Nearly two years ago we ran a nameberry contest asking you to guess the name of Ben Affleck and Jennifer Garner‘s second child; now the challenge is to come up with the name of Affleck pal Matt Damon and wife Luciana‘s fourth daughter, due to be born any minute.

　　Matt and Luciana have two daughters together, Isabella, age 4, and Gia Zavala, 2, in addition to Luciana‘s daughter from a previous marriage, Alexia.  You tell us: What’s the new Matt Damon baby name?

　　Will the new baby’s name harmonize with her big sisters’ stylish Latinate names, or strike out in a new direction? Will the new baby have a surname as a middle name, as do Gia (Zavala is a common Spanish last name) and Matt himself (his is Paige), or, like Isabella, no middle name at all?

　　To everyone who guessed early and chose a boy’s name, before I heard the news that the baby is definitely a girl, you get another shot: I can tell who you are.

　　The person who guesses the new Matt Damon baby name correctly wins a full signed set of our baby name books, including The Baby Name Bible, Cool Names, Beyond Ava & Aiden and Cool Irish Names. If no one guesses the name exactly, we’ll choose the winner by whoever comes closest, in the opinion of the judges aka Pam and Linda.

　　A bit about the names of the Damons’ children: All three are rising in popularity and have a Latin feel, undoubtedly thanks to mom Luciana‘s Argentinean roots. Gia is a short form of such Italian names as Gianna, Giovanna, and Giada, first known in this country via 60s movie star Gia Scala, born Giovanna. Most recently, it’s gained notoriety as the oldest stage-bound daughter of Real New Jersey Housewife Teresa Giudice.

　　Isabella, the Spanish and Italian version of Elizabeth, is both classic and mega-trendy – it’s now the most popular name in the U.S. Alexia, a more modern offshoot of Alexandra/Alexandria, has also been steadily rising along with other members of the Alex family.

　　Those characteristics offer some good clues to what the couple’s fourth baby might be named. Or do they?

　　Post your entries here; one to a customer. Since everyone started with first names only, let’s keep going that way. Check and make sure someone hasn’t already entered your guess, as the first one to claim a name will win the prize. Different spellings counted separately, so if someone has already guessed Sofia, you can guess Sophia. (But sorry, those two are already taken.)

　　Adding a middle name does not mean you get to reclaim a name — so if Sophia has already been guessed, you can’t guess Sophia Rose. You also can’t guess two names — i.e. “Sophia or Sofia” — or both guesses will be disqualified, though if you’ve made any of those mistakes before I wrote this — 7:19 a.m. EST on October 12 — you get to choose ONE of your “or” names or reguess if you’ve guessed a double name already guessed by someone else.  The computer logs the time you post, so who gets what first is free from human error.

　　Phew! I better stop now or the rules will be longer than the entries. Everyone clear?

　　Entries accepted until the minute before the baby’s name is announced.
