did you ever find the answer to your questions? I too am from the Jesse/Dinah Hollingsworth Moody line. I decend from their daughter Elizabeth. I don't have an Iaasac in my information would be nice to have the entire list of children.
I don't have a lot of information on their children but what I do have I will gladly share. Just know in advance that I personally haven't proven any of this except through Elizabeth's line.
