Avraham Reznik, born in Mir, was married to Roza Klackin. The couple lived in Uzda with their two children, Rachel and Dov (Beretzke). After Roza drowned in a river, Avraham married Chasia, Roza's younger sister. In 1919 the family moved to Mir. Avraham and Chasia bore four sons, one of whom, Irshle (Zvi), died of illness at the age of three. Chasia also raised her sister's children, Rachel and Dov.
In Mir, Avraham owned a flour mill and electric-power station, and the family lived well. His brother Moshe lived in the house next door. Avraham was a Zionist, and raised his children in the same spirit. His sisters, Henia and Sarah, emigrated to Eretz Israel in 1924. His sons Dov and Yitzhak were members of "Hashomer Hatzair," and in 1938 Yitzhak (later Razin) emigrated to Eretz Israel and joined the Ben Shemen youth village. That same year, Rachel, the daughter of Avraham and Roza, married Gershon Iskolski, and the couple settled in Mir. In 1939 their daughter Roza'le was born.
When WWII broke out, Dov Reznik left Mir to join the Zionist training camp in Vilna. In June 1941, following Nazi Germany's invasion of the USSR, he returned to Mir.
On the second day of the Nazi invasion, Avraham Reznik was murdered in Mir by a local resident. He was buried in a mass grave in the center of the town. On 9 November 1941, during the "First Massacre," Avraham and Chasia's two younger sons, Melech and Eliyahu, were murdered.
On the night of Sunday 9 August 1942, a few days before the "Second Massacre," some 200 Jews escaped from the Mir ghetto to the forest. Among them were some members of the Reznik family: Rachel, Dov, his girlfriend Pesia Szklar, Moshe Reznik and his son Israel. Rachel left her young daughter Roza'le with her Chasia, who pled with Rachel to save herself, but Rachel could not abide leaving her daughter and returned to the ghetto the following day. The others joined the partisans. On 13 August 1942, during the "Second Massacre," Chasia Reznik, her sister's daughter Rachel Iskolski (nee Reznik) and Rachel's two-and-a-half-year-old daughter Roza'le were murdered.
Dov and Pesia survived the Shoah, and when the war ended they went to Poland. Their firstborn son Avraham was born in Lodz. The family ended up in Italy, where they awaited emigration to Eretz Israel at the Ostia DP camp. In 1947, the three arrived in Eretz Israel, where their son Mordechai (Moti) was born.
Moshe Reznik lost all his family. His wife Esther (née Brochneski) was murdered during the "First Massacre" on 9 November 1941 in Mir. His younger son Zymel was killed in Mir in 1942. His older son Berel fell as a soldier in the Red Army in 1942. Israel, who joined his father in the forest, was killed during battle as a partisan. Moshe Reznik survived and emigrated to Eretz Israel after the war. There he married for a second time, raised a family, and continued his work from his days in Mir as a scribe.
