Edward is an old-fashioned baby name making the rounds once more as it grows in popularity. It comes in at number 261 for American baby boys so far in 2018 and means, "guardian of prosperity."
It's certainly been favored by royalty, and the youngest of Queen Elizabeth's children is named Edward,
Prince Edward, Earl of Wessex to be exact. But for an actual heir to the throne, Edward would conjure up memories of a former king named Edward. For those rusty on history, King George V died, leaving his son Edward VIII the crown. However, Edward didn't live up to his role very well. He ascended to the throne in 1936 and became somewhat sympathetic if not enamored of the Nazis. Then he fell for an American woman who was a married socialite.
She later divorced and Edward made it clear he intended to marry Wallis Simpson. The royal family, the country and the church made it clear they weren't on board. Thus, in 1937, Edward abdicated the throne, famously stating, according to History.com, "I have found it impossible to carry the heavy burden of responsibility and to discharge my duties as king as I would wish to do without the help and support of the woman I love." Thus Edward is not a prime option for a new royal son.
