Saw your request for information. I have tracked the Dart family for some time, specifically the Daniel Dat branch and the William Dart of Harpersfield branch. My stems from the second branch, but since the other branch is in Vernon and Bolton, CT, where I live, I have delved into that. There was a rather large book on the Dart family by Thadeus Bolton. It lists the family of William of Harpersfield. However, he has them linked to the wrong branch. I have obtained the necessary documents that prove he is the son of Roger Dart. They are included in the report that will be sent.
I did find the birth record of Esther in Watertown, CT, but never found any more on her. Neither did Bolton. I would love to obtain what ever information you have on Esther and her family.
I have tracked back from Richard of New London over to Devon, England. There are records for that, but nothing specifically ties our New London Richard into them. It is a little bit of conjecture, so I have not included it in the file. I do have a record from the Ship Amity that states Richard came to the Americas at the time he showed up.
