William and Kate Share Unseen Photo of Queen Elizabeth II With Family

The Prince and Princess of Wales are honoring Queen Elizabeth II in a special way.

On what would’ve been the late monarch’s 97th birthday, Prince William and Kate Middleton shared a never-before-seen family portrait of Her Majesty sitting beside some of her youngest grandchildren and great-grandchildren.

Alongside the photo shared to their official Instagram April 21—snapped by Kate herself—they noted, “This photograph – showing her with some of her grandchildren and great grandchildren – was taken at Balmoral last summer.”

As for the royal breakdown of who exactly was in attendance? Though Queen Elizabeth had eight grandchildren, it was her youngest two—whose parents are Prince Edward and Sophie, Duchess of Edinburgh—that are seen standing in the back row: Lady Louise Windsor, 19, and James, Earl of Wessex, 15.

Meanwhile, out of the Queen’s 12 great-grandkids, William and Kate’s three children, Prince George, 9, Princess Charlotte, 7, and Prince Louis, 4, alongside their cousins, Isla Phillips, 11, (whose dad is Peter Phillips) and Lena Tindall, 4 (whose mom is Zara Tindall) stood right in the middle.
