its most likely both german and dutch! (many of the words are very similar, more even then german/english words, and there are many of them (in spite of the very under used 'words from german thread') Pennsylvania had a large immigrant german population, NY had a Dutch population and both added place names.

did i mention that yesterday was NY 340th or so birthday? (the date is from the incorportion date, the settlement was some 25 years old before it was incorporated-- and that date is really for Nuew Amsterdam, not NY)
