British Prime Minister David Cameron and his wife, Samantha, have named their new baby daughter Florence Rose Endellion, which honors their Cornish roots. The couple’s vacation in Cornwall, near the village of St. Endellion, was interrupted when Samantha went into labor Wednesday morning. Florence is their fourth child; her living siblings are Arthur Elwen, 4, and Nancy, 6. Their son Ivan died at the age of 6 last year after suffering from cerebral palsy and epilepsy. Florence, weighing in at 6 lbs 1 oz, wasn’t due until next month. “She is an unbelievably beautiful girl, and I'm a very proud dad,” Cameron said, who added he and his wife wanted to honor Cornwall. “Both baby and mum seem to be doing very well, so it's really exciting."
