Queen Elizabeth. Liz. Her Majesty. British monarch. Lilibet.: The queen has more names than P.Diddy (or is it Sean Combs now?) but we recently realized that we didn’t know the 95-year-old’s full name. Or even just her last name, for that matter. So, we did some digging and it turns out that there’s way more that goes into her official moniker—Elizabeth Alexandra Mary Windsor—than we thought.
Let’s start with the easy stuff. Elizabeth is the eldest daughter of Prince Albert (George VI) and Lady Elizabeth Bowes-Lyon. Hence, her first name. Liz was given her middle name, "Alexandra," after George VI's mother, who had passed shortly before her birth, and "Mary" after her paternal grandmother, Mary of Teck.
So, where does "Windsor" come from? According to the official website of the royal family, before 1917, members of the family had no surname “but only the name of the House or dynasty to which they belonged.”
King George VI was born in 1895, as a member of the House of Saxe-Coburg-Gotha, and he and his family used the name up until 1917, when the royal House was changed to the House of Windsor. (Elizabeth Alexandra Mary Saxe-Coburg-Gotha would have had quite the ring to it, though.)
