“Once We Were Slaves — The Journey of a Multiracial Jewish Family” lecture: 7 p.m. Monday, CU Boulder Norlin Library, 1157 18th St., Boulder. In this talk, Professor Leibman overturns the reclusive heiress’s assumptions about her family history to reveal that her grandmother and great-uncle, Sarah and Isaac Brandon, actually began their lives as poor, Christian and enslaved in Barbados. Leibman traces the siblings’ extraordinary journey around the Atlantic world, using artifacts they left behind in Barbados, Suriname, London, Philadelphia and, finally, New York. While their affluence made them unusual, their story mirrors that of the largely forgotten people of mixed African and Jewish ancestry that constituted as much as 10% of the Jewish communities in which the siblings lived.
