Joel is already a member of the site. I wanted you to consult with him about it in case he thought you might get anything out of being a member. We are looking for researchers and/or those who have confirmable data.
The material you saw on LDS sites was all put there by one person, who has no proving documents to connect anyone in Europe with anyone in the US. Though much of the information is valid (or probably valid) the method of presentation is misleading since good, connected lines are mixed in with pure guesswork.
