Norse naming conventions are pretty cool. You could use a germanic suffix word like weld/wold/etc to add to the end of a descriptive word. Often it may well just describe the forest by size, ownership, bounty (what it offers) or some more mythical connotation.

I like your hand-drawn map but then I like most. You conundrum reminds me of why I like working digitally these days too though. Nothing beats the undo/erase function. =P
