I recently requested a copy of a coroners inquest from PRONI for the death of my half brother in the 60's. All the information I had to give was the date and place of death. Took a while but eventually they got back to be and unfortunately the inquest had been destroyed at some point in the past

apparently they only keep important ones! But the man from PRONI was really helpful and sent me a scan of the entry in some file recording verdicts (misadventure) and then out of the blue a few weeks later he emailed me a copy of the post mortem! Which actually answered all my questions as it had a lot of information about the circumstances- which my father rarely would speak of -
He was nearly 11 years old, collecting birds eggs with his friends on a stretch of beach, he became separated from his friends and they began looking for him at 5pm when it was time to go home and couldn't find him. They left at 6pm and my father rang the police at 8pm. His body was found at around 8pm by a dog walker at the foot of a rocky outcrop, but the man couldnt reach him so ran for the the police who arrived and recovered him at 8.20.
Sorry for the long reply, just trying to suggest a copy of the postmortem aswell as I wouldn't have requested it!
