Aäron van Praagh was married to Judith van Praagh-Polak. The couple lived at 44 Emmastraat in Rijswijk. When they were picked up together with their child, the SD stole a few items of jewellery from them.
The archive of the Stichting Sieraden-Comité contains a list of the stolen items of jewellery, a declaration under oath and a statement of the right to inheritance.
