Bummer on Hillside. Wallington is just across the river from Passaic County. Clifton and Passaic both have Jewish sections and I am pretty sure the one cemetary on the Clifton/Passaic Park border is Jewish. There is the big one in Totowa with the most amazing stones and stained glass in the masoleums - its Mount somebody, maybe Nebo... and there is a tiny one next to interstate 80 Totowa/West Paterson/Little Falls? I pass on the way to work each day. its so tiny and lonely but all the stones have the little rocks on top so I hope someone is remembering them.
Good Luck!
