It's used as a euphemism for drowning or shipwrecks in which the sailors' and ships' remains are consigned to the bottom of the sea - to be sent to Davy Jones' Locker.
The origins of the name of Davy Jones, the sailors' devil, are unclear, with a 19th-century dictionary tracing Davy Jones to a "ghost of Jonah". One theory is that Davy was the corruption of a West Indian word for devil and Jones referred to the biblical Jonah who was swallowed by a whale.
The earliest known reference of the negative connotation of Davy Jones occurs in the Four Years Voyages of Capt. George Roberts, by the author Daniel Defoe, published in 1726 in London.
"Some of Loe's Company said, They would look out some things, and give me along with me when I was going away; but Ruffel told them, they should not, for he would toss them all into Davy Jones's Locker if they did."
