Hello Listers, I am looking for my grandfather's great uncle. His aunt's mother was Anna Amalie Koelliker - b 7 Mar 1831, Thalwil, Zch., md 27 Aug 1855 to Karl Rudolf ZELLER. The only info that have on him that he was Praesident, von Hirslanden. I anyone working on the Zeller line and can anyone tell me where Hirslanden is? Any info would be greatly appreciated. Alice from Las Vegas
