If your grandmother happen to know his birth month & birth year you can go to PeopleFinders.com and type in his first & last name and birth month & birth year and see what comes up. The state is not necessary. (If you don't know the birth month but know his birth year you can try that also)
If you find any listing write down the city/states where he is found (sometimes there is more than one city/state) and then go to

This website gives you information on how to contact them to obtain information from military records. If you happen to know when he enlisted in the Navy (or how long he had been in)and where he enlisted or what state in the U.S. he lived, that helps.
Military terms are usually 2 years (not sure if they still have the 2 year terms any more) or 4 years and some continue on reenlisting for 4 more years each time until retirement at 20 years up to 30 years.

Just thought I would include this information on the US Trout. I'm not sure if you know when the ship left London but in August of 1959 the US Trout was reasigned to Charleston South Carolina in the U.S.
You can type in the name of the submarine and find a picture of it also. example: US Trout Submarine Picture or Picture of US Trout Submarine.
The contract to build Trout was awarded to the Electric Boat Division of General Dynamics Corporation in Groton, Connecticut on 14 May 1948 and her keel was laid down on 1 December 1949. She was launched on 21 August 1951 sponsored by Mrs. Albert H. Clark, the widow of Lieutenant Commander Albert H. Clark, the last commanding officer of Trout (SS-202). The boat commissioned on 27 June 1952, with Commander George W. Kittredge in command.
Trout operated out of New London, Connecticut, as a unit of Submarine Squadron (SubRon) 10 from 1952 to 1959. During this period, she conducted training and readiness operations with ships of the fleet and NATO nations, operating from the North Atlantic to the Caribbean Sea. She engaged in sonar evaluation tests, practice ASW exercises, and submerged simulated attack exercises. During submerged exercises in polar waters in company with sister ship Harder (SS-568), Trout sailed 268 miles beneath Newfoundland ice floes, setting a distance record for a conventionally-powered submarine.
In August 1959, Trout shifted her home port to Charleston, South Carolina, where she was assigned to SubRon 4. She was deployed to the Sixth Fleet in September 1959 for her first Mediterranean Sea cruise. Four months later, while returning home, she represented the United States at Bergen, Norway, during the 50th anniversary celebrations commemorating the birth of the Norwegian Navy's submarine arm.
In February 1960, Trout performed as a test bed for Bureau of Ships shock tests. She won her first Battle Efficiency "E" award in 1961. In early 1963, the submarine rendered services for the Operational Test and Evaluation Force before commencing a six-month overhaul at Charleston, South Carolina, in July of that year.
During the remaining years of the 1960s, Trout made three more Mediterranean deployments as a unit of the Sixth Fleet. Between deployments, she participated in training and developmental exercises off the east coast and in the Caribbean Sea. In July 1970, she was assigned to the Pacific Fleet.
Homeported at San Diego, California, Trout conducted two Western Pacific (WestPac) deployments, one in 1972 and one in 1975, primarily providing submarine services during ASW exercises conducted by warships of the United States, South Korean, or Nationalist Chinese navies. Between these deployments, the submarine participated in antisubmarine warfare exercises and conducted local operations off the southern California operating areas, punctuating this service with weapons tests in the Pacific Northwest, out of Puget Sound.
After returning from her second WestPac deployment to San Diego, California, on 29 January 1976, Trout enjoyed a brief unusual duty—repeatedly diving and surfacing while being filmed. She appeared as the fictitious nuclear submarine USS Neptune in the opening credits of the movie Gray Lady Down. She then received orders on 1 December changing her home port to Philadelphia, Pennsylvania.
In 1977 and 1978 Trout was extensively overhauled. On 19 December 1978, with new engines, and new batteries in excellent materiel readiness, she was decommissioned, struck from the Naval Vessel Register, sold to the Shah of Iran, and renamed Kousseh. Her Iranian crew took her to New London, Connecticut, but abandoned her there in March 1979 following the Iranian Revolution. She was retained at Philadelphia, Pennsylvania while finances were resolved, then returned to United States custody in 1992.
