Norman Miller, who arrived in Britain via the Kindertransport when he was 7 years old, died Feb. 24 in a hospital in Manhattan. He was 99.

In 1944, when he was 20 , he joined the British Army, hoping to find out what had happened to his family in Germany. Not until after the war did he learn in a letter from a friend who had survived the Jungfernhof concentration camp that his parents, sister and maternal grandmother had arrived there in late 1941, were shot to deaths and buried in a mass grave. Mr. Miller and his son Steven traveled to Riga in 2013, saw the remnants of the camp and went to the forest to fill three vials with soil from the killing fields.

At Mr. Miller’s burial in Paramus, NJ, his sons and other family members poured the soil from his vial onto the coffin after it was lowered into the grave. In his eulogy, Steven Miller said that the purpose of sprinkling the coffin with the Riga soil was “so that they, who were torn from him and never had a proper burial of their own, can finally be prayed over and reunited and laid to rest with their son.”
