Hi, my 3rd great grandfather was Jemima's brother, Isaac. I have a great deal of info on the Nettleships which was provided to me by William and Jemima's 2d great granddaughter. However, your info was new to me as I didn't have the ship's names. Thanks. If you want to contact me directly, please email me at email@example.com Another "Cuzin" and I are doing this research together and we are both excited to see your posting.
