Those are the in the apostrophes quiz in Steve's link, not the pub quiz one in mine. You did make me think I was goung mad since I was thinking what godfather one, what Jesus one???
Sorry, my mistake. I only skimmed your question and thought you were referring to the apostrophe one.
The one about Cambridge I worked out from "ponte" (meaning bridge) at the end of the name.
I figured out the long words one by elimination. It looked like a numerical thing, which eliminated swamps and if it had been seven, it wouldn't have had all the unaccounted for syllables in the middle.
Also, the tortoise one, I had no clue, so went for the obvious answer.
You could also probably get the OS map one by elimination, but I knew it anyway.
