Can anyone tell me if this cemetary still exists? My grandmother was buried there in the late 1950s and I wonder if it woud be possible to visit it. Thanks for any info!

I searched google.com, and it looks like there is more than one gate of heaven cemetery in NY State.
Is it the one in Westchester County?
If so, this may be it:
10 West Stevens Ave
Hawthorne NY 10532
914-769-3672
