Hi Pol,
I have indeed a SCHOCH line in the Swiss part of my genealogy. But it is very older than yours: 1550-1600!!!
I do not know if we are related. It is possible but I ignore how we could be related.
FYI, my SCHOCH line is from the area of Obfelden, not very far southwards from Zürich.
Bye from France,
