This happens to be the first time that the COSTON spelling for CAUSTON has come up.Phonetically,it fits. The message I picked up seemed to be part what I submitted and part of another person's message,so am not sure to whom I am replying .This is the first time I have seen a connection to Schoonover,also.I have thought perhaps there was a Hugenot connection--as the spelling could be French.Write again and I will better understand both the message and the sender.
