The Lesser-Sonnenthal family lived in Berlin prior to emigrating to Holland in the 1930s. Annemarie's mother Tilly-Sonnenthal Frank was in Barcelona prior to arriving in Amsterdam in July 1938, where she may have participated in the Spanish Civil War. The fate of her husband (Annemarie's father) Hermann is unknown.
