Henry Thomson was born in Holland and shipped when he was 15 years old. Henry served 14 years in the United States Navy and six years in the merchant trade. He was last at sea on a U.S. Naval Vessel as Quartermaster in 1868. Henry’s last residence before entering Sailors Snug Harbor was 15 Hamilton Ave in Brooklyn, New York. He lived there as a Bachelor and had no wife or children.

Henry Thomson entered Sailors’ Snug Harbor on February 3, 1900, and would remain at the Harbor for four years and 25 days. He died and was buried in Sailors’ Snug Harbor Cemetery, Plot 9, Row 6, Grave 23, which gives Henry a grave number of 2434 from the cemetery map.
Henry Thomson asked the Governor of Sailors’ Snug Harbor to dispose of his items after death as a gift to the Destitute Children of Seamen Society. “I hereby request that in the event of my death, any personal effects I may leave be turned over to the Home for Destitute Children of Seamen” ( Henry Thomson’s Registration Page). This society for Destitute Children of Seamen was next to the Sailors” Snug Harbor. It is possible that while staying at Sailors’ Snug Harbor, Henry observed these children at the orphanage and wanted to do something for them.
