I am currently researching all descendants of Johann Wilhelm Robert Grässer, born 23 September 1857 in Ottenhausen (or Zürich, according to some documents). He married Amalie Tschan in abt. 1883 and after her death on 27 February 1893, Luise Rufer, born 3 August 1878.
At the same time I am trying to find more information about my ancestors. Especially the ancestors of the people mentioned above.
Any information would be appreciated. I am also willing to share the information that I have.
