Thank you for the kind comments, Mighthelp. I am aware that you too have helped many with their searches in Eastern Europe.
In this case the 2 postings (2006 and 2012) appear to be for a Wademan family from England and not connected to the original Wedmann family from Volhynia. I browsed through all of Richard Moore's postings. All were in 1999 though one was a response in 2002. There is no doubt that his ancestry tracks through Volhynia but his postings contain convoluted info that in some cases are simply not accurate. I'm sure I could help him if he was still interested. I found his email address in one of the postings but it is associated with a .com address which no longer exists so I doubt that sending an email would help but I will try just in case.
