It was September 2, 1886 and the following came from Yankee Trader, a novel by Robert L. Merwin:
"A big dance last night in Bassin by Mrs. William Behagen for her grandson Mr. Louis Knuttesen (isn't the hospital in Christiansted named after someone with this same name?) from Edinburgh where he has been educated to be a doctor and is now out here on a visit to his grandmother. Mrs. Behagen is a colored lady, wife of Mr. William Behagen, a tall lanky colored man who keeps a Rum Shop in Company Street, Bassin though Mrs. Behagen-whom all call Miss Jane-is the boss. The family is greatly thought of in the community. Bishop Branch calls upon her whenever he comes here, I understand, and is generally tendered a sumptuous lunch. Governor and Mrs. Arendrup also make official calls upon her."
There is more information but too long to write here. These folks may be your relatives!
