I recently moved to a neighborhood in Astoria Queens known as Dutch Kills.
The word "kill" is is derrived from a Dutch word meaning "creek" or "stream". As a consequence of our roots as the Dutch colony of New Amsterdam, a lot of places in NYC and the surrounding part of New York State contain "kill" in their names. Peekskill, NY comes to mind, as does Great Kills on Staten Island.
Considering what "kill" means in English, adding "Kills" to your town name might give it the same sort of creepy play on words feel that Darkness Falls has.
