Young Owen William Oâ€™Donnell will never be allowed forget the day and the time he was born.
The son of Donna and Tony Oâ€™Donnell arrived at the South Tipperary General Hospital in Clonmel at 4.24pm on Monday, July 22.
At the same time in St. Maryâ€™s Hospital in Paddington, London, Kate Middleton also gave birth to a son, the future king of England.
â€œHe is greatâ€, Owenâ€™s mother Donna told radio presenter Hector Oâ€™hEochagain on his Breakfast with Hector programme on 2FM on Tuesday morning.
The new arrival weighed in at 6lbs 2ozs, a couple of pounds lighter than the Duke and Duchess of Cambridgeâ€™s first child, who weighed 8lbs 6ozs.
Owen, who shares his second name with the Duke of Cambridge, is a second son for the Oâ€™Donnells, who are from Cahir.
Donna was admitted to the hospital at 1.30pm on Monday and the baby was born three hours later.
She said on Tuesday morning that she was also doing absolutely fine and was looking forward to going home.
â€œThe Irish royal babyâ€ has caused quite a stir and Hector Oâ€™hEochagain visited the Oâ€™Donnells at the Clonmel hospital.
While the Oâ€™Donnells wasted no time in naming their new arrival, the new English prince had yet to be named up to Tuesday afternoon.
