FAMILY TREE: Queen Elizabeth II, Queen of the United Kingdom and the Commonwealth and Prince William's grandmother. MEANING: Elizabeth is of Hebrew origin and means God's promise or God is my oath. WHY WE LIKE IT: Why wouldn't you want to be named after one of the most powerful women in the United Kingdom? Even though sources report that the couple has decided to use Elizabeth as one of two middle names, Elizabeth not only honours the baby's great grandmother, but Kate Middleton's middle name is Elizabeth as well.

FAMILY TREE: King George VI was King of the United Kingdom from 1936 to 1952. MEANING: Originally of Greek origin, the meaning of George is "farmer". Also there is the story of Saint George, a knight who became the patron saint of England and achieved legendary status after his struggle with a fire-breathing dragon. WHY WE LIKE IT: Besides being a dragon slayer, the name George goes back to the Royal family's history books since 1660. George VI was also the last male figure in power — this title currently belongs to Queen Elizabeth II.

FAMILY TREE: Princess Diana, The Princess of Wales and Prince William's mother. MEANING: Diana is derived from either an Indo-European root meaning 'divine' or from the Latin word 'diviana.' WHY WE LIKE IT: After Princess Diana's tragic car crash in 1997, Diana would be a wonderful tribute to remember Lady Di. Again, sources say the couple plan on using Diana as a middle name, but we would love to see Diana used as the first name.

FAMILY TREE: Prince William, Duke of Cambridge and father. MEANING: William is of Old German origin and means protection. WHY WE LIKE IT: Maybe a reason to follow in his father's footsteps, William Jr. may be a suitable name if the couple had a baby boy. Prince William has always been known for his good grades, his love for sports and being a philanthropist.

FAMILY TREE: Princess Margaret, Countess of Snowdon, was Queen Elizabeth's sister. MEANING: Margaret is of Greek origin and means pearl. WHY WE LIKE IT: Keeping it in the family, we like that fact that Princess Margaret was the Queen's youngest and only sibling. Margaret lived a life of controversy when it came to her love life and divorce, but she was remembered for her affection and love for her family, according to The Telegraph. Plus, so many good nickname possibilities!

FAMILY TREE: Princess Diana's mother's name was Frances Shand Kydd. MEANING: Frances, which comes from old French, means to be free. WHY WE LIKE IT: Another way to keep a grandmother's name in the family, authors have described her as "certainly complicated" but also "funny, warm, intelligent and energetic," according to The Daily Mail. We also like this name because it could be used both for a baby girl or boy.

FAMILY TREE: Queen Victoria spent 63 years on the throne. MEANING: Victoris of Latin origin and means victory. WHY WE LIKE IT: Queen Victoria continues to be the family's longest reigning monarch and the longest reigning female in power. As a child, she was known as a "patient rebel" — always aiming to be "good" but also very strong-minded, according to Professor Lynne Vallone.

FAMILY TREE: Charles, Prince of Wales, father of Prince William. MEANING: The name is Old German and means free man. WHY WE LIKE IT: Staying true to a father-son bond, royal sources have said that Prince William has been very supportive of his father and that they share a closer relationship, according to the Telegraph. Who knows, maybe this is a trait that will continue with Prince William's son.

FAMILY TREE: Actually, this name isn't in the family — but it could be. MEANING: Jason means the healer. WHY WE LIKE IT: It may not be part of the Royal family's family tree just yet, but "Fledgling Jason Steed" is one of Prince William's favourite books, according to The Daily Mail. The story follows an 11-year-old boy named Jason Steed who is destined to save himself and his country from a nuclear threat.

FAMILY TREE: Okay, we're throwing this one out there but hear us out. MEANING: Smythe is Old English for 'blacksmith.' WHY WE LIKE IT: Kate Middleton has been seen donning a Canadian-made Smythe blazer several times, including during the 2012 London Olympic Games. And who doesn't like the sound of Smythe for a baby girl? At least it doesn't rhyme easily.
