Ben Affleck and Jennifer Garner have finally named their second daughter Seraphina a week after she was born.

Seraphina Rose Elizabeth Affleck was born on January 6 in a Los Angeles hospital. Her name is derived from the Biblical word 'Seraphim' and means 'fiery ones'.

Founder of BabyNames.com, Jennifer Moss, said, "Seraphina is a beautiful name — based on the Seraphim, the highest order of angels. I'm not a fan of the double-middle name, but it's nice they continued the «flower' theme by including the name Rose."

Affleck and Garner, both 36, already have a three-year-old daughter called Violet. They began dating in 2004 and were married a year later. They had previously starred together in 2003 superhero flick Daredevil.
