I share my names with many royals, from the past to today. And I bet there will be more little princesses with these names.
My first name is Sofia, so there is for example Queen Sofia and Infanta Sofia of Spain, from the British royal family Sophie, Countess of Wessex and many other royalties were or are named Sofia, Sophia, Sophie. For exemple, one of Princess Josephine's (Denmark) names is Sophia.
My second name is Elisabet. It is the Finnish form, without the H as in Elisabeth or Elizabeth. I think I don't have to name some female royals with this name, you all know them. Elizabeth I, Elizabeth II, Queen Mother, Princess Elisabeth of Belgium and so on. Elisabet is also a popular second name for royalties.
I just love my names, but they are really popular in Finland, especially for people in my age (17). Sofia is a popular first and second/third name and Elisabet(h) is a popular second/third name.
