It's a interesting list - somemof the words are familiar to me - especially the ones from the northern counties. I've never heard "Marlock" in Lancashire, though. Possibly it's common in the southern part of the county. Up here, in Northn Lancashire, they are more likely to say "laikin" for play, practical joke, etc. It is even more common in WestYorkshire. The word is Scandinavian, and in current usage in Denmark - prolly parts of Norway, too.

I'm immortal until proven otherwise
