Everhardus Jacobus Wijtvliet was a son of Alida Velleman and the non-Jewish Everhardus Wijtvliet. After the birth of his sister Saartje in May 1920, Everhardus Jacobus was born in Haarlem on 9 November 1921. His mother Alida Velleman however passed away already on 17 October 1924, when Everhardus was hardly 3 years old. And there was also a little girl, his sister Grietje, who died in February 1924 too, so his father was all alone in caring for the children. On 25 March 1925 his father married again to Trijntje Zwiers from Blokzijl, 19 years old and born in Blokzijl, a daughter of Antsje Zwiers.
Everhardus Jacobus lived at home for some time, but was sent on 1 March 1935 to “De Kindersluis” at Oudedijk 291 in Rotterdam. De Kindersluis was an observation home and daughter-association of Pro Juventute. According to an item in the Leidse Courant of 5 January 1939 at the occasion of the delivery of a new building, the aim of De Kindersluis was the temporary custody, care and accurate observation of boys who are sent to the association by the public authorities (and also by associations and guardianship councils). The age of the patients varies from about 10 to 20 years.
When Everhardus Jacobus arrived on 1 March 1935 in De Kindersluis, he was nearly 14 years old and he stayed there for some months. On 7 July 1935 he left from there for Haarlem, where he came living at Oudeweg 57b. February 1941 he moved to Amersfoort. Still Everhardus Jacobus Wijtvliet died in Haarlem on 4 March 1943, 21 years old and there has been drawn up certificates of death for him in Haarlem as well in his residence Amersfoort.
