Gustaf Wennström is born in Wänneböke, Hinneryd parish. Also Johan Svensson and his father Sven Månsson are born in Wänneböke. So I suppose their family names are coming from that village. I don't know if they are related. Johan Svensson is a distant relative to me, but I have noticed his wife namn as Gustava Jönsdotter born Nov. 30 1838. I can send you more about the ancestors to Johan Svensson by email. Regards Leif
