The Queen's great-grandchildren: A who's who of the youngest members of the British royal family

Queen Elizabeth II isn't just the British monarch – as both a grandmother of eight and a great-grandmother, the royal is also the matriarch of an ever-growing family! In fact, in 2018, the Queen spoke of the royals, and it seems they are just like us! At Christmas, for example, the great-grandkids "love knocking" ornaments off the tree, the monarch revealed in the ITV documentary The Queen's Green Planet. "They enjoy themselves," said the Queen. "And the great thing is to make them decorate [the tree first] and they're a bit more careful." With her granddaughter Zara Phillips expecting her seventh great-grandchild in 2018 and granddaughter-in-law Kate Middleton welcoming great-grandchild number six on April 23, meet the Queen's great-grandkids – Savannah, Isla, Mia, Princess Charlotte and Prince George, who calls Her Majesty 'Gan-Gan' – and learn their places in the line of succession.

Princess Charlotte Elizabeth Diana of CambridgeBorn: May 2, 2015Like her elder brother George – and, it is expected, her baby sibling – the Princess came into the world in the Lindo Wing. The expectant Duchess of Cambridge's daughter, whose middle names reflect both her great-grandmother Queen Elizabeth II and grandmother Princess Diana, is fourth in line to the throne. Because of the changes to succession law in 2015, Charlotte cannot be displaced in line of succession by any future younger brothers. Photo: Getty Images
