There is no cemetery in Hasbrouck Heights.

Another cemetery to check out is George Washington Cemetery on Paramus Road in Paramus, Bergen, NJ.

You may try to contact "The Observer" which is a local newspaper for obit notices. They used to be located on the Boulevard (which is the main street in town). I don't know how old their archives are.

Or you may try the local library which has many books and, I believe, microfilm on the local newspaper.
