Hi
I'm guessing you might have come across this already but here is a good resource if not:
http://www.islandregister.com/yankeegale.htmlHaving researched my ancestor's link to a whaling ship disaster, I found local newspapers to be a great help in terms of giving details of the ship. However, I was lucky that my man was a Captain. However, you may find details about your ancestor in the smaller local papers that might want to connect their community to a bigger story.
The manifest and the log book for my ship disappeared. Whether due to the wreckage or later on, I have no idea. But, they would not be a priority to save in a crisis.
Good luck with your search.
