Incidentally, I've always considered my surname to be of Scandinavian origin. My Dad's family come from Formby just north of Liverpool, which is traditionally considered to be a Viking village. The -by at the end is a bit of clue for starters. My favourite explanation is that "Rimmer" means "Poet" and comes from the same root as "Rhyme". So I was very interested to learn recently that there is a traditional form of Icelandic poetry called "Rimur". Draw your own conclusions...
