Hi,
Yes, I have traced the Hirchfeld connection to vorarlberg and thanks to the museum (Dr Eva-Maria Hesche?). I have some photo-copies of how the Hirschfeld family tree connects. I dont know how much about the man who left that community or why?
I will be on holiday near Geneva at the end of July so its possible I could make it to Austria for the reunion - not sure at the moment
Do you want to know about how descendants in Scotland or the McKerrel (his wife) side?
My direct email address is Nigel 'dot' Richardson 'at' mail.com whats yours please?
