Born in 1899, the merchant James Stock from Posen/West Prussia married Johanna Moses from Wetzlar in Wiesbaden. The couple lived in poor conditions in a backyard apartment at Walramstraße 31, a street with a dense "Eastern Jewish" population. Their children Josef and Rosel were born during this period of long-term unemployment and ever-increasing National Socialist policies of exclusion.

In 1939, the parents and five-year-old Josef and two-year-old Rosel were forcibly committed to a barrack in the Mühltal homeless settlement. As part of the ghettoization policy, the family was forced to move to the "Jews' house" at Ludwigstraße 3 in 1940. The parents managed to place their son in the Jewish children's home in Neu-Isenburg in 1941, before this last refuge was also closed.

On June 10, 1942, Josef and Rosel Stock were "evacuated to the East" together with their parents. Around 380 people, mostly entire families, were deported to Lublin-Majdanek via Frankfurt am Main, where a further 600 people boarded the train. Over 100 men fit for work, including James Stock, were selected for a labor detachment. Exhausted, these men were then murdered in the Majdanek concentration camp. In the neighboring Sobibor extermination camp, Josef and Rosel Stock were asphyxiated in the gas as soon as they arrived.

In 1995, at the suggestion of the Green Party in the Mitte local advisory council, part of Kronprinzenstraße/corner of Bahnhofstraße (formerly Cecilienplatz) at the municipal kindergarten was renamed "Geschwister-Stock-Platz" to commemorate the approximately 40 Jewish children from Wiesbaden who were murdered by the National Socialists. The daycare center also bears this name.
