The Middleton Family have a book that provides information on all the the descendents of Ann Eaton and the Middleton family. There was a group of 27 families that immigrated from Yorkshire England of which Robert was one. They settled on the first lots when they arrived. The book does provide information to all the descendants of the families to the 1970's
They are my 4 or 5 times Great Grandparents. I am sure you can obtain a copy of the book today.
