Hi again. I tried Sofield and there were none. After you gave me the name of Soper I checked that and sent what we had. There are no listings for a Sopher. If all the data matches except the name, chances are the Soper men are yours. It could be also that for indexing purposes, the spellings are generalized but the actual paper will have the true spelling.
Let me know if I can help further.
