I just moved >from Norfolk to central New Jersey, but if you are talking
about the Hebrew Cemetery Section of Forest Lawn Cemetery than you may
call them at (757)441-1752. They are very nice and helpful and have a
card file of all the burials right there in the office and can look it
up for you immediately.
I have a map of the burials in the Mikro Kodesh cemetery but the is no
Westheimer buried there.
Good luck in your research.
