Willemien Rieken (died 24 July 2020) was a Dutch woman who was in September 1945 one of the Flower Children after the Battle of Arnhem, aged 9. Children who lived near the scene of the fighting at the time were given an Allied war grave to maintain. Rieken adopted it ever since and looked after the grave of Trooper William Edmond from Musselburgh. She looked after the grave for over 75 years, until her death.
