278 (or more) people died in a fire at the Brooklyn Theatre in 1876; 103 of them, "whose remains were so charred that they could not be identified, whose bodies were unclaimed, or whose family could not afford private burial, were interred together" here in Green-Wood.

Thanks for the link. I had heard of this fire but never read any accounts of it. What a tragedy.
