surfing along genealogical sites I met your message about Carl Christian Sartorius. My uncle Hugo Sartorius (A.H.E.P)born 19-10-1895 at Amsterdam , published 1939 a 'Genealogie Sartorius- Darmstadt). As far as I know the book is also accepted in the statelibrary in Mexico-City. Hugo visited 1950 the "Sartorius Hacienda Mirador Äccording to his genelogy Carl C Sartorius born 31.8.1796 at Gundershausen is a grand-grandson of Johann Daniel Sartorius born 7-7-1684 at Nauheim,who as also my ancestor. He was a minister. His grandfather was also a Theologican and changed his name SCHNEIDER (taylor) in SARTORIUS. Inhis "genealogie Sartorius"Hugo spends several pages to Carl Christian Sartorius. Hope this will help a bit. Edu Sartorius (Nederlend).
