I have Martin Risch born 27 Oct 1810, son of Christian Risch and Anna Mathis;,married Anna Hitz daughter Henrich Hitz of Saab on 06 July 1845; and died 06 March 1866. This was taken from the Conters church registers. I also found records for the baptisms of the children you listed except for Barbara. I will look and see if I can find any other marriage records for Martin. Let me know if you want anything else looked up. I have the Conters records and access to at least part of Saab. I am researching Risch from Conters...the family of Anna Risch who married Johannes Braun in Chur.
