Holy Name cemetery burial index is online
There are no ages listed though. If you find someone there you can get the age from the microfilms or send me an email from my website.
Holy Cross cemetery also on the rcan site is very close by and many from Hudson County were buried there.
St. Peter's cemetery in Jersey City is also on the microfilms and if you checked the first two cemeteries I can check St. Peter's for you.
