Thanks for that information. Roy Clinton Wann is buried in Elk City, Oklahoma. I have of photo of him with one of his bird dogs....he was somewhat famous as a hunting dog trainer....close by, in case anyone is interested in seeing it as an attachment.
If you would, can you put me touch with your father. I would like to see the lineage he has. I had several discussions with a Wann from Indiana and also in Australia, and there is some disagreement about the very earliest lines in America.
