"Flowers of Bermuda" came about when we took him to the old Dockyard...now much restored,,,back then it was just the museum part and some 'work in progress' buildings...
The artifacts in there stirred Stan's interest as did the pictures of maritime scenes..
There was a map of shipwreck sites on the wall...there was the 'Nightingale"...
and the North Rock, that had claimed so many vessels...and the song was born.

North Rock, Bermuda: 32°28'26.47"N, 64°46'6.96"W

Odd. The usual Bermuda wreck websites are fairly complete for the period. None I could find list a Nightingale. Anybody know more about the map/wreck mentioned above?

If it be the same vessel (big if), the USS Nightingale (1851) was a fairly well known New Englander by W.L. Hanscom of Maine. Her Swedish backer named her after Jenny Lind with a figurehead to match. She had been a China clipper; African slaver; Pacific telegrapher and Union collier. She was out of Liverpool, bound for Halifax, in general cargo service when she foundered in an April 1893 North Atlantic storm.

Hitting The Rock would have her many hundreds of miles off course to the south.
