Until now it had remained a cherished family photograph, unseen by the rest of the world. Showing the Queen and the Duke of Edinburgh surrounded by seven of their great-grandchildren at Balmoral Castle, the precious image had been kept under wraps. But Prince Philip’s death at the age of 99 on Friday has prompted the 94-year-old monarch to open the treasured royal family album in memory of a beloved patriarch. The image, taken by the Duchess of Cambridge in 2018, shows the Queen holding baby Prince Louis in her arms as she sits between his brother Prince George, now seven, and sister Princess Charlotte, five. Peter Phillips’ daughter Savannah, 10, their eldest great-grandchild, stands behind the couple as her younger sister Isla, nine, cradles their cousin Lena, the two-year-old daughter of Zara and Mike Tindall, whose eldest Mia, seven, flanks them and seemingly stifles a giggle. Speaking a thousand words about the Queen and the Duke’s close bond with the youngest members of the House of Windsor, the image captures the relaxed mood as the children visited Great Granny and Grandpa in Scotland that summer. It was taken almost a year before the Duke and Duchess of Sussexes’ son Archie, their eighth great-grandchild, was born. The Duke and Duchess of Cambridge also issued their own separate photograph, taken three years earlier at Balmoral, showing the Queen and the Duke posing with an infant George and baby Charlotte.
