well, i was having this problem last night (i'm editing a chapter book for my younger cousin's birthday and i needed cool but not-too-weird names).
then i found this great site: pseudo-Elizabethan place names. it's fun just to see all the stuff it comes up with. check it out here!
ok. yes. i am a total forest fanatic. it's part of why i love fantasy so much. but seriously, aren't these pictures amazing?
