A week after their second daughter’s birth, Jennifer Garner and Ben Affleck have announced her name, Garner’s reps tell PEOPLE exclusively.

It is Seraphina Rose Elizabeth Affleck.

The baby was born Jan. 6 in Los Angeles. Garner and Affleck, both 36, are also parents to daughter Violet, 3.

While no explanation was offered for the name, or if she was named for anyone, one Web site specializing in the origin of names refers to Seraphina as “derived from the Biblical word ‘seraphim,’ which was Hebrew in origin and meant ‘fiery ones.’ ”
