Born last Dec. 15 in London and revealed as a PEOPLE exclusive, Nell Burton had a gestation period for her name almost as long as the pregnancy itself. The creative couple had difficulty agreeing a moniker.
Bonham Carter, 42, confirmed the name during a phone interview with the Jewish Journal while on the set of Terminator Salvation in New Mexico.
Bonham Carter said her daughter was named Nell after "all the Helens in the family." The actress's mother is named Elena and her grandmother was called Helene.
The name originated during medieval times and is a diminutive of Helen. It was also widely popular in the U.S. at the start of the 20th century.
Rumors had surfaced previously that the baby was named Indiana Rose, however the reports were never confirmed by the couple, and a friend tells PEOPLE, "Her name was never going to be Indiana Rose."
Bonham Carter has now wrapped filming, and the family, along with four-year-old son Billy, is on vacation with partner Burton – who celebrates his 50th birthday on Aug. 25. Later this year the actress will appear on screens in the next Harry Potter movie.
