Hello, Susan - great to find another direct von Thun descendant! if your daughter is interested, we can fill in more than a few generations of von Thun ancestry. Elisabeth von Thun's father Peter was born 14 Dec. 1825 in Bokel, Kirchspiel Bramstedt, Hannover, Germany. He married Anna Sorg in London before travelling onwards to New York. Peter's brother Hinrich stayed in London and was my g-g-grandfather. Peter's and Hinrich's parents were Lühr Hinrich von Thun and Gesche Fedderwitz. Their family tree is available on German genealogy sites: in fact several trees, managed by Nadine Ramm, Rita Bömermann, Bernd Salewski, Johann Wellmann and others.
