Greetings WW I Researchers:
The NY State archives include the roster of names and descriptions of soldiers who served in the "Nine" during WWI. The archive entitled "Harlem Hellfighters" offers digitized records of the men who served in the Regiment.
The database is searchable by name and what a find! I found one soldier whom I've been researching for quite some time.
The url will take you to the page. Just click on the folder entitled "Harlem Hellfighters." Please note that the url is very long. If you get timed out, then just backspace until you can enter the page.
Enjoy your search and find New York City's legendary "The Nine."
