This woman rescued 2500 Jewish children from Warsaw Ghetto risking her own life. She was nominated for Peace Nobel Prize Award last year. I would love to present that great heroic Polish catholic woman to you all. To me she is a real saint!!!!! She is still alive, now 98 years

Ghetto was a place of isolation for Jewish people in Warsaw occupied by Nazi , which Jews were not allowed to leave. Many Jews were killed there for nothing , or from there transported to Auschwitz camp where certain death awaited them. Irena went there and persuaded Jewish parents and grandparents to place their children in her care.

Smuggling the children past Nazi guards through a variety of means – hiding them in body bags or under loads of goods – Ms. Sendler took them into the homes of Polish families, where they were adopted and raised with false identities. Ms. Sendler made lists of these children and placed the lists in a jar that she buried in a garden, hoping she could someday dig up the jar, locate the children and inform them of their past.

From 1942 to 1943, Ms. Sendler managed to smuggle 400 children out of the Warsaw Ghetto before she was captured by the Nazis and severely punished for her actions. Even under extreme torture, she refused to reveal where the lists of the smuggled Jewish children were hidden. Eventually, a member of the Polish underground bribed a guard to release her, and she entered into hiding. Even then, she continued to work with Zegota to rescue another 2,100 children.

 The Ulma Family, citizens of Markowa , gave their lives for  helping Jews. In 1942, Germans murdered the majority of the Jewish citizens of this small village in southeastern Poland.
Still a few months later some other families made a heroic decision to hide the remaining  Jews . The Ulmas were one of them. Eight Jewish people found shelter in their house, including a family of six people. Although  they lived on the outskirt of the village, the Nazi found out about Jews kept there and  on March 24, 1944 they arrived at the house of Jozef Ulma. There were soon thereafter a few shots heard -- the Jews were killed first, then the parents and finally the terrified kids -the oldest of whom was 8 and the youngest 1,5. Actually the youngest martyr was the seventh child in his mother's womb, who was murdered just a few days before the day of his planned birth.

Owing to the help of other Poles who kept Jews in their houses until the end of the war, at least 17 people survived in Markowa.

The Ulma family has been honored with the title Righteous Among the Nations, and their beatification process was initiated on the diocesan level in August 2003.
