Question: Can you tell me a good resource besides the U.S. Navy to research a submarine my ancestor served on in World War I.
Answer: One of the best resources for that sort of question is the Submarine Force Museum in Groton, Connecticut. They maintain a collection of records, and photographs of all American Submarine vessels. Their scrapbook collection is very impressive.
