Victoria College pupil Peter (11) and nine-year-old Susannah performed the Gratitude of the Young in the annual ceremony before the Queen and senior members of the Royal Family in the Royal Albert Hall.
The ceremony was screened live on BBC 1.
They were chosen because the organisers wanted to emphasise the Occupation of the Channel Islands in this 60th anniversary year.
As the children, from St Mary, walked across the hall to the stage, presenter BBC newsreader Huw Edwards announced their names and said that 60 years ago their grandmother, Betty Hucker, witnessed the liberation of the Island by British forces.
Susannah, a pupil at Jersey College for Girls, was carrying poppies to lay on the Book of Remembrance.
