Over 75 years ago, a woman hid and cared for a Jewish teenager and their siblings during the Holocaust. This week, she met their children.

The large Mordechai family might never had existed had it not been for now 92-year-old Melpomeni Dina.

40 descendants of a group of Israeli siblings had the opportunity on Sunday to meet face-to-face with the woman who had saved their family, CBN News reports.

It was a time of hugs and tears as Dina was able to see for the first time the result of her kindness so many years ago. Having done so, the elderly woman says she can now "die quietly."

Gatherings and reunions of this type are becoming less frequent as the ages of Holocaust survivors and rescuers become more advanced, but the reunion between Dina and the Mordechai family is a reminder of the amazing acts of kindness by many to save those at risk of death due to their Jewish heritage.

Sarah Yanai is 86-years-old and the oldest of the five siblings who was hidden, fed, and protected by Dina and others during the Second World War.

"The risk they took upon themselves to take in an entire family, knowing that it put them and everyone around them in danger," says Yanai with gratitude. "We are now a very large and happy family and it is all thanks to them saving us."

Around six million European Jews were massacred during World War II by German Nazis and others. More than 27,000 has been recognized as "Righteous Among the Nations" by Israel, the country's highest honour to the individuals who risked their lives to save Jews during the time of the Holocaust. Dina was among around 355 individuals from Greece to have received this honour.

Israel's Yad Vashem Holocaust memorial honours those who harboured Jews during the Second World War by engraving their names an avenue of trees. Only a few hundred are still alive today.

Since 1992, the Jewish Foundation for the Righteous has hosted reunions such as that between Dina and the Mordechai family. Executive Vice President Stanlee Stahl, however, believes the time for these events is nearing its end.

"This is probably going to be our last reunion, because of age and frailty," says Stahl, who adds that this reunion was particularly emotional.

"Either the survivor has passed on, the righteous has passed on or in some instances either the survivor or the righteous gentile is unable to travel," she says. "You see the survivors, their children, their grandchildren, you see the future. To me it is very, very, very special. In a way, a door closes, one opens. The door is closing ever so slowly on the reunions."

The Mordechai family was living in Veria, Greece during the time of the Second World War. The area's entire Jewish community was exterminated in a matter of months. In early 1943, Jews in the area were being gathered for deportation when non-Jewish friends of the Mordechai family provided them with fake identity cards and hid them in the attic of an abandoned Turkish Mosque.

The family spent a year in hiding there. They say that during that time, they could hear the terror of what was happening to other Jewish people outside. Eventually, the family had to leave due to health concerns.

At that point, Dina, who was a seamstress, and her two sisters took in the family of seven. Though they themselves had little food, they cohabitated in a single-room house on the city's edge. One of the children, Shmuel, became sick and was taken to hospital despite the risk of him being found out. He passed away there at the age of six.

Not long following Schmuel's passing, Dina and her sisters helped the family flee to different areas, providing them with clothing before they left.

The family finally reunited and traveled to Israel after liberation. There they began to start their own families.

"They fed us, they gave us medicine, they gave us the protection, everything, they washed our clothes," says Yossi Mor, who was an infant at the time when he was hidden by Dina. Now 77, he recollects some of what took place during that time.

"She loved me very much."

Approximately 400-500 cases are recognized each year for the title of "Righteous Among the Nations." The process brings healing, reunion, and a chance to reconnect Holocaust survivors with the rescuers who put everything on the line to save them.
