Dear Jim, I have worked alot on the Thomas line. Bob Sheldon has done the most since he was the associate historian for that line on the update books. I have a corrected Thomas on the SFAA webpage for the first three generations in this country and will have the fourth done soon. Take a look. If you can add to it let me know. Contact Bob Sheldon to see what he has. My line is Thomas at the moment but I have a feeling from new information that it will be switching to John Jr. Just love it when you find a child misidentified. Oh well, Martha
