Former "Bachelorette" star Becca Kufrin introduces her baby boy and explains the story behind his name, Benson Lee Jacobs Kufrin. Some of her followers question why Kufrin's last name is listed last in the double surnames. In Spain and other Spanish-speaking countries, it's customary for women to keep their last name, followed by the father's surname for their children. In the United States, it is more common for married couples to give the baby the father's last name. Kufrin hasn't clarified her reasoning, but she is known for breaking tradition and doing things her own way.
