At least, that's what researchers at family history website Ancestry.co.uk are betting on.
The site's researchers delved into the names of the couple's ancestors, looking for a moniker we might hear when the royal baby delivery news is finally announced, according to the UK's Daily Mirror.
On the more "exotic" end of the spectrum, the Duke and Duchess of Cambridge could name their baby Hyancinthe or Theophilus after one of their ancestors.
Or, they could stick with a more common name like Elizabeth and John—both of which are the most popular names in both of their respective family trees.
While it's still up in the air as to when Middleton will give birth to the royal baby, Middleton and Prince William did leave her family's home in Bucklebury earlier today, and it's expected they will head back to London.
Which could be the first sign that the royal baby will be on its way sometime soon.
Although initial reports claimed the baby was due July 13 or 14, the U.K.'s Telegraph reported that the duches is due today, and that hospital staffers were told to be on standby for Middleton's delivery as early as a month beforehand.
And this isn't called the Great Kate Wait for nothing.
Even Queen Elizabeth II is in limbo over the baby news, saying recently, "I would very much like [the baby] to arrive because I'm going on holiday."
The Queen is expected to start her summer vacation in Scotland next week.
And perhaps she'll get her wish.
Duchess of Cornwall, Camilla, told well-wishers Monday that the family expects Middleton to give birth "by the end of the week."
"We are all just waiting by the telephone," she added. "We are hopeful that by the end of the week he or she will be here."
