Were you born on the same day as the Queen? If so, Belfast City Council wants to hear from you.
Ahead of the Queen's 90th birthday celebrations, a city-wide search has been launched for a Belfast pensioner born on April 21, 1926.
The imminent nonagenarians have been invited to join the festivities surrounding a beacon lighting in the grounds of City Hall.
Anyone who knows someone born on this date can email the council at email@example.com.
When the Queen reaches her milestone, she will light the first of a chain of more than 1,000 beacons at Buckingham Palace.
In Northern Ireland, beacon lighting ceremonies will include a cross-community service at St Macartin's Cathedral in Enniskillen. Two intersecting beams of light will shine hundreds of feet into the night sky to represent the two communities.
Members of Army Cadet Forces will make an adventurous tribute by climbing to the top of the four highest peaks in the UK to light beacons. These include 850 metre Slieve Donard in Co Down, Ben Nevis in Scotland, Mount Snowdon in Wales and Scafell Pike in England.
