Alida Tas was a daughter of Eliazer Tas and Eva Lamon, who were married in Amsterdam 10 May 1876. Alida had four brothers and one sister, namely Salomon from 1878, Hartog from 1880, Philip from 1883, Rachel from 1888 and Isaac from 1890. Her father, Eliazer Tas, a diamond broker, was born in 1857 and passed in 1928, almost 71 years old. Her mother, Eva Lamon, born in 1853, died in 1934 at the age of 80. Both were interred in the Jewish Cemetery at Muiderberg. Salomon and Rachel have died already before the war; Hartog survived the war but the others were killed in the Shoah. It was special that the complete Tas family and relatives have attended the 50th wedding anniversary of her parents at party centre Huize Stranders in Amsterdam. And also Claartje Blom, the servant maid, who lived in with the family already since her younger years.
Alida Tas married Asser Sondervan on 19 August 1909 in Amsterdam, a son of Nathan Philip Sondervan and Helena Cohen. After the wedding they lived at Hemonystraat 33 3rd floor in Amsterdam. In April 1916 they moved to Cilliersstraat 39 ground floor and in January 1924 to nr. 31. When the Sondervan family moved in 1932 from there to Pretoriusplein, Alida’s mother Eva Lamon and her brother Isaac moved into that house. Later the domestic servant Claartje Blom came living in there too. In July 1938 they moved again – now to Paardekraalstraat 13 1st floor in Amsterdam, which became their last known address in Amsterdam too.
The Sondervan couple had three children: in 1910 Philip Asser (Flip) and in 1913 the twin Evalina (Eva) and Helena (Leni). Flip was married in 1937 in Amsterdam to Rebecca Elise Nanatte Cohen Paraira (Betty). She had been an au-pair with an uncle in Brussels. They had two children in 1939 and 1943 and by hiding in Belgium they all have survived the Shoah. After the war they had two more children. Also the twin Eva and Leni survived the Holocaust. Philip Asser Sondervan passed away in 1959 in Amsterdam, his siblings Eva in 2009 and Leni in 2001.
On 14 November 1942 Alida Tas suffered from a cardiac arrest and died at home when her daughtger Leni was picked up from home and arrested. She worked for a photographer, who was suspected of illegal activities by the Germans. However Leni was allowed to remain at home to take care of the funeral. Afterwards, she went into hiding and later fled with her sister Eva l to Belgium. They were not welcome there to an uncle in Brussels and then ended up in Namur, where they were protected/ hidden by a Catholic priest (Joseph Endré).
Alida Tas was interred at Muiderberg. Her husband, Asser Sondervan was detained in barrack 58 on 18 March 1943 in Westerbork. Five days later, on 23 March, he was put on transport to Sobibor and on arrival there 26 March 1943 immediately killed.
