THE Duke and Duchess of Cambridge were not the only parents to welcome a new addition yesterday.

Two south Essex families also had babies born on the special day.

First-time mum Wioleta Wilamowski gave birth to a baby boy at Basildon Hospital exactly 60 minutes before the new prince was born and weighing almost the same.

Taking his paternal grandfather and father’s names, little Jan Krystian Wilamowski was born at 10.02am, weighing 8lb 6oz.

After a 30-hour labour his overjoyed parents, who live in Grays, were pleased to be able to tell family that their son shares his birthday with a Royal.

Hayley Keys, 31, of Rayleigh, also gave birth to a little boy, Ross Jr, at Southend Hospital.

She said: “I knew the royal baby was coming today.

“It’s lovely that Ross shares his birthday with a prince and that it is on St George’s Day.

“Like Kate and William we didn’t know we were going to have a boy either and he was the same weight, 8lb 7oz.”

Dad Ross added: “We can’t thank the incredible staff and teams on the wards and in theatres at Southend Hospital enough.”

Ross Jr also has three “very excited” older sisters, Alysha-Rose, eight, Lili-Rae, seven, and two-year-old Orea-Mia.

The girls unfolded the family’s new arrival from a white towel to reveal their baby brother to great delight.

Her Royal Highness gave birth to the couple’s third child at the Lindo Wing at St Mary’s Hospital in London.

A spokesman for Kensington Palace said: “Her Royal Highness The Duchess of Cambridge was safely delivered of a son at 11.01am.

“The baby weighs 8lbs 7oz.

“The Duke of Cambridge was present for the birth.

“Her Royal Highness and her child are both doing well.”

The arrival of a prince was a surprise for the Duke and Duchess, who chose not to find out the sex of their baby in advance.

Like George, the baby is a Prince of Cambridge, after the Queen stepped in to ensure that all children of the Royal couple were given the title Prince or Princess.

Changes also mean the young prince is also no longer allowed to jump ahead of older sister Charlotte in the line of succession.

Previously, he could have taken precedence over Charlotte, and leapfrogged into fourth in line.

But a radical shake-up of the royal succession rules removed discriminatory male bias and will mean that Charlotte remains fourth in line to the throne.

A name has not yet be chosen for the royal youngster, but royal commentators have suggested that it is likely to be a traditional name. The bookies’ favourites at the moment are Arthur, Albert, Philip, Frederick and James with the couple now having a George and a St George’s Day baby.
