Yesterday he arrived, and now his name is finally here! In line to be king after his grandfather and father is George Alexander Louis of Cambridge, it was announced around 1:15 p.m. EST Wednesday.

But why were those names chosen?

George was a given favorite, as it is the Queen's father's name: "There have been many more king Georges in recent centuries than any other name, so I think they went for tradition on that one—but broke with tradition in terms of giving him three names instead of four," Nameberry's Pamela Redmond Satran told The Huffington Post. Though she is surprised about the other two names: "I think Alexander and Louis in the middle place, versus honoring [George's] father, grandfather or great-grandfather, is a departure."

The Alexander part of the name was also one of the top choices for the baby's first name (and reflected as such in betting circles on the royal baby), but its significance potentially comes from the traditional naming for the old kings of Scotland, according to USA Today. It's also the male version of Queen Elizabeth's middle name.

And finally, there's the Louis. Where does this come from? We'll have to go to the Queen's husband for a hint at this name. It's a reference to Prince Philip, Duke of Edinburgh's uncle, Lord Louis Mountbatten.
