"Family Matters" is a non-fiction book that explores the history of the Rescher family, which emerged in the 17th century around Lake Constance. The Rescher family played a significant role in the founding of the Jewish community in Hochberg, which thrived from 1750 to 1850. The book highlights the fates of family members who found a path to prosperity and Germanization before most of them emigrated to America in the 1850s. The narrative also includes the remarkable exception of the Orientalist Oskar Rescher and his successor Osman Reser, who lived as a convert to Islam in Istanbul. This work provides a deep insight into the cultural and religious changes the family experienced over the centuries and illustrates the connections between Europe and America in a historical context.
