In Plymouth, Tobago, lies a tomb with an enigmatic inscription:

Within these walls are deposited the bodies of Mrs. Betty Stiven and her child. She was the beloved wife of Alex B Stiven to the end of his days will deplore her death which happened upon the 25th day of Nov. 1783 in the 23rd year of her age. What was remarkable of her, she was a mother without knowing it, and a wife without letting her husband know it except by her kind indulgences to him.

Theories abound, but there’s no consensus as to its meaning.
