Grace, who was the seventh of nine children, was born in 1815, in Bamborough, and when she was a little girl of eleven years her father was given charge of the new light on Longstone Rock, which was one of a series of dangerous reefs where no vessel ever built could live when a gale was blowing.
The tiny microscopic animals that secrete this polypary live by the billions in the depths of their cells. Their limestone deposits build up into rocks, reefs, islets, islands. In some places, they form atolls, a circular ring surrounding a lagoon or small inner lake that gaps place in contact with the sea.
When Grace was a young woman of twenty-three a terrible storm burst suddenly upon the coast and in the twinkling of an eye the reefs about the lighthouse were a sea of churning foam, while the great waves racing in from the ocean thundered so mightily at its base that it seemed as though they must tear it from its foundations and sweep it away.
