Can you please tell me how to locate what section a grave may be located in. Is there an online database to search if there is a relative buried there.

Looking for Joseph Savino died April 20,1970

They do have an online database. but when they tell you where the grave is it's kind of cryptic. However with that information you can call anyone at the cemetery. When you get there, there are notes on the doors of the mausoleum with a phone number you can call and someone almost always answers right away; even if you have to leave a message you get an answer very quickly. https://www.rcancem.org/find-a-loved-one-search/
