The names of "George VI 1895-1952", "Elizabeth 1900-2002", "Elizabeth II 1926 - 2022", and "Philip 1921-2021" are included.

The small internment chamber beneath the memorial chapel was supposed to hold her remains.
The remains of Princess Margaret were placed in the royal vault of St George's Chapel, but transferred to her parent's tomb under the King George VI Memorial Chapel in April 2002.
The chapel was commissioned by Queen Elizabeth II in 1962 as a final resting place for her father, King George VI, who died suddenly in 1952.
The larger royal chapel is located between the buttresses of the north wall of the quire of St George's and the chapel.

Queen Elizabeth II, who personally met the £25,000 cost of the project, was said to prefer a flat ledger stone, inlaid into the floor, over a marble chest tomb with large effigies.
The names and dates of Queen Elizabeth II and Prince Philip can be found on the new stone.
