Graves

My wife and I have discussed this a couple times. With 100’s of years of verifiable occupation to some level or another, it seems odd to me that they haven’t found a grave site at some point. I mean, people have to have died on the island before now (The Curse). Did they always take the dead away? Mining accidents, farming accidents, illness, exposure, old age. There’s a million non-conspiracy ways it could happen. Thoughts? Discussion?
