Preinfalk is a variant of Breinfalk where Brein means 'mush, porridge' but I can't figure out what the whole name means. You can find their distribution in Germany at

I don't know the origin of Cutforth but Goldworthy and Halfpenny are both placenames, the former in Devon and the latter in Cumbria.
