I can prove my following remarks, but not me, my father, Rudolf, born in August 1903 explained in Forbach in Lorraine, our name came from the Middle Ages, where to find a bitching and moaning as K yffer described. Over the years the spelling has changed. Others claim it was a typical craftsman's name and come from K ü fer, the maker of wine barrels, has said here, too, as amended by the well-known reasons the notation: could not many people read and write, except the priest, who led the church books and the names wrote to Gehöhr! - If someone asks me today where the name comes, then I say he came from the tree Supplied in K! For as whingers I would not be called and no one knows the cooper's more ... !
