USS Wampanoag fast cruiser
I recently became interested in the fast American cruiser USS Wampanoag, laid down in 1863. The purpose of the Wampanoag class was to catch the 16 and 17 knot blockade runners built in Britain that were trying to enter Southern ports. David Dixon Porter was in an internal political struggle with Benjamin Isherwood and succeeded in stopping the construction of these ships until they no longer had a mission. the Wampanoag apparently could sustain 16.6 knots and could be pressed up to 17.75 knots, making her the fastest American warship until the USS Charleston was completed about 20 years later. This is my edited Wampanoag photograph and I did a Springsharp design:

Do you know of any source that would offer a name log of the crew of the old HMS ships? Specifically, I want a source of information for the Royal Battleship HMS Agamanon. Can you point me in a direction? I have a clock with a placard that says it was presented to a fellow from the workmen crew on the HMS Agamanon and dated early 1900's.
This is a link to online records search for Royal Navy personel:

You may be able to find the sailor by searching at this page.
Thank you! I will let you know if I find the family name.
