I am naturally very happy that you guys are pushing on with the search.
Hopefully it will turn-up something meaningful.
My minor worry is, why would a Rev. by the name of Raasch, in the last known location of the man in question, acknowledge the fact that his father had visited me in Selkirk all these years ago, if in fact this man was not his father.
It seems to me that we have the right family, ay least one member of that family, and he ain't talkin !!!!
