I am descended from the Shunn's of Bedford. My branch of the family emigrated to Ontario, Canada in 1847. There were also Shunn's about the same time in Wilts but I am not sure if/how they were related. I know of at least one Stephen Shunn born ca. 1770 in Bedford. I have a few odds and ends about the family that are connected to London. I don't know if I can help you or not but I would be interested in comparing notes.
