I don't know of any such sites, however you do not say anything about what kind of information you are looking for. If you were more specific it would be easier to give advice.
My great grandfather left England -I think maybe Liverpool with his Uncle & Aunt in 1852 or 1853. According to his newspaper obituary they were shipwrecked enroute and had little food when rescued. They were rescued by a passing ship and taken to a New York port. The Aunt & Uncle lost 3 small children on the trip. I want to learn more about the ship wreck.
This looks like a question which should have a better chance at TheSHipsList, see the link in the left frame to learn how to subscribe to that mailing list.
