World Exclusive: Historians predict royal baby will be born on 27th august 2013

GenesReunited historians use marriage and birth records to predict the date of William and Kate’s first child

Amidst all the gossip and speculation, a team of historians from, the family history website, have predicted the birth of the Duke and Duchess of Cambridge's first child will be on the 27th August 2013.

Analysing birth and marriage records of the Royal family from the past 100 years, has calculated 851 days is the average period between a Royal wedding and the arrival of a Royal baby. Conception would therefore be around Christmas this year.

Rhoda Breakell, head of said: "There's certainly been a lot of speculation about when the arrival of a Royal baby might be; the bookies are even taking bets on names. William and Kate have spoken about their desire to start planning for a family, so make sure that you put the 27th August 2013 in your diaries, we have a good feeling about this one!"

A history of Royal births

The shortest period between a Royal wedding and a Royal baby was that which followed the wedding of HRH Princess Patricia of Connaught and Capt. Alexander Ramsay on 27th February 1919. The newly-wedded couple had their first child, Alexander, only 298 days later. In contrast, the longest period of time was that which followed Prince Henry's marriage to Lady Alice Montagu-Douglas-Scott on 6th November 1935; they made the nation wait 2235 days before the birth of their son William on 18th December 1941.

Prediction of 851 days and baby name to be confirmed

So what does one call one's Royal bundle of joy?

As Royals in line to the throne, William and Kate's baby will need a name worthy of a King or Queen, but could Kate's 'commoner' background have influence? Analysis of the prevalence of previous royal family names, and those in Kate's family reveal some possible options the young couple might be considering:

Girls names Boys names
Carole Charles
Elizabeth George
Mary Henry
Philippa James
Victoria Michael

Breakell added: "It'll be interesting to see if William and Kate choose a modern name or a more traditional one like their ancestors before them. Royal weddings and Royal births are big events, so one thing we can be sure of is there will be a national celebration when Baby Windsor does arrive."
