Some were quick to comment on the historical significance behind the name, while others opted to share strong opinions.
After arriving at St. Mary’s Hospital in London on Monday, Kate Middleton gave birth to her third child with Prince William at 6 a.m. EST. The couple then introduced Prince Louis to the world outside the hospital’s private Lindo Wing just as they did with their first two children, Prince George and Princess Charlotte.
