This year, the theme for Holocaust Memorial Day is Untold Stories
The anniversary of the liberation of the Nazi Auschwitz-Birkenau concentration camp on 27 January 1945 is been marked by Holocaust Memorial Day.
The day aims to remind the world not only of the events leading up to and during World War II, but of subsequent genocides too.
This year, the theme for Holocaust Memorial Day was Untold Stories.
Ben from Deal's great-grandmother died in a concentration camp in WWII.
The postcard in the loft
After his mother died, Ben found a postcard in the attic. It was sent from his great-grandmother who was being held in a camp in Germany. He decided to find out more about her story.
Lucie Lasker send this postcard from Riebnig - a transit camp in Germany
Ben's great-grandmother was Lucie Lasker. She was in Riebnig, a transit camp, where she had been taken following the removal of most of the Jewish community from the town of Breslau in Germany.
"They wanted to clear the Jewish community not just because they wanted to murder them, but also because they needed their accommodation for soldiers and refugees," said Ben.
Every few weeks groups were from taken from the Riebnig camp back to Breslau and after a few days they were put on trains to the extermination camps.
"All is now at an end"
"What we do know is that there was a very, very rare opportunity to write a postcard," said Ben. "My great-grandmother duly did write a postcard to a relative in Sweden and from Sweden the postcard found its way through to England to my mother."
The postcard gave some news that Lucie was out in the country, she was not able describe the terrible conditions there but at the bottom she wrote: "All is now at an end."
"For us that is the significant message," said Ben.
"She had seen her friends and relatives being deported on the different transports and she knew that she was going to be next."
Lucie Lasker was taken to Theresienstadt. Although the camp had no gas chambers, people were given no food and they lived in appalling conditions.
At her age and in those conditions, Lucie would not have been expected to live long.
"We understand that she died within two weeks of coming to that particular concentration camp," said Ben.
"If my great-grandmother can serve as a example as somebody who was very ordinary, but somebody whose story we understand a little bit more, then it might help us to actually understand and bring to life some of those thousands and maybe millions of people whose stories will never be told."
