This is an interesting point. Names are often older than they appear.
I have a book on Greek mythology that takes the position that Hercules, including his name, is considerably older than most of the Greek pantheon and should be thought of as a foreign import. But the form of his name ("Heracles") looks so natural in Ancient Greek, "glory of Hera" in the same way that you see other Greeks named Agathocles or Themistocles, that the mythology around the relationship between Hera and Heracles, which is extensive, must have developed from that apparent similarity.
Potentialities like this keep us on our toes when we look at names like "Rungholt".
Absolutely, though in this case it would be the most obvious translation, since it was a frisian settlement and "Rung" and "Holt" are both frisian words in use. It is possible that Rung here could mean stanchion/post (so for wood that makes strong posts), but unlikely so close to the sea, is it not?
I get what you mean, though. Here is a village called Großenwiehe, easy to be translated as "Great Consecration", and that was the commonly accepted meaning. Only much later it became apparent that "-wiehe" probably came from wighæ, so "Great Fortification". And in fact the old fortifications are still visible today.
