The Queen and Philip were much loved by the royal great-grandchildren. Their 12 great-grandchildren are Savannah, Isla, George, Mia, Charlotte, Prince Louis, Lena Tindall, Archie Mountbatten-Windsor, August Brooksbank, Lucas Tindall, Lilibet Mountbatten-Windsor, and Sienna Mapelli Mozzi.
Lili and Sienna were born in the months following Philip's death. Unfortunately, the Duke and Duchess of Sussex have remained in the US, where they live with two-year-old Archie and nine-month-old Lili.
