''"In order to avoid deportation, the parents of seven-year-old Margaretha Celine (Greetje) de Haas (later Gosschalk) handed her over in August 1943 to a nurse who was active in a nurses’ Resistance group. The Resistance group was connected with an underground movement in the province of Groningen, and Hendrik Jager was one of the people who traveled to Amsterdam to maintain contact between the two groups. Hendrik’s main task was to find families willing to hide Jewish children. He would wait at the train station in Groningen and then escort the children either to the address he had found or, temporarily, to his home until a permanent place could be located. Since he had not found a family who would take her, Hendrik decided to take Greetje in himself and she stayed with him and his wife, Geesje, for three years. Hendrik and Geesje lived in Hoogezand, Groningen, and had two sons, Henk and Bernd, who regarded Greetje as a sister.
