Leopold Reis and his family members

I am searching for any information about Leopold Reis, born 1903, and his family members. Leopold Reis married my sister Diethild (Hilde) Gerechter in Dec. 1941.

Leopold Reis and his family moved to Berlin from Freudenberg/ Baden in late 1939. His mother was Babette, his siblings were Isak and Jeanette Reis, who married a man named Mayer. Leopold Reis had to do forced labor for the Neuköllner Kabelwerke until 1942, Diethild for Riedel de Haen in Britz.

Further, maybe someone remembers my sister Paula Gerechter, who did forced labor for the Siemens-Schuckert-Werke, Kleinbauwerk, Spandau. All of them were deported and murdered in 1942 and 1943. I would be grateful for any information.
