The discovery of a small silver pendant has finally revealed the poignant fate of Holocaust victim Karolina Cohn.

Archaeologists confirmed that the young girl and her family died at Sobibor extermination camp after they found an amulet inscribed with her name and birth date on the path to leading to the gas chambers earlier this year.

After decades of uncertainty shrouded the fate of the Cohn family, relatives were finally able to pay tribute to them at a memorial ceremony on Monday (13 November), reunited by the German girl's pendant.

The triangular amulet bears the Hebrew phrase "Mazel Tov", Cohn's birthplace (Frankfurt) and her date of birth "(3 July 1929). It is an almost exact replica of the pendant owned by Jewish diarist Anne Frank, who died in Bergen-Belsen concentration camp after her family's hiding place in Amsterdam was revealed to the Nazis.

Both girls were born and went to school in Frankfurt and died in concentration camps when they were 14 and 15.

Historians are currently investigating the ties between Cohn and Frank and trying to locate relatives of both girls as they piece together whether the pair knew each other.

After matching the pendant inscriptions with information on Nazi deportation and transport lists, researchers at the Yad Vashem, the World Holocaust Remembrance Center, got in touch with Cohn's relatives, many of whom live in the United States.

Dozens travelled to Frankfurt to commemorate Cohn and her family outside the building where they lived before they were deported on 11 November 1941.

Four memorial plaques, designed by German artist Gunter Demnig, were unveiled at the ceremony and relatives gave speeches.

A minimum of 250,000 Jews, mostly from Poland, the Netherlands and Slovakia, are estimated to have been murdered at Sobibor between April 1942 to October 1943.
