Don't want to be a party pooper but the song contains the line

"October night was such a night as was never seen before"

Storms are frequent along the east coast, such as the one that wrecked the Whitby lifeboat in 1861 or the one that caused the most dramatic rescue of the Visitor from Robin Hoods Bay in 1881. Thus is it by no means guarenteed that your gravestone relates to this song.
