Not to take anything away from Gilbert Cope and his work(s); GENEAOLOGY OF THE DUTTON FAMILY OF PENNSYLVANIA and THE DUTTONS OF CONNECTICUT. The immigration lists have more than 42 Duttons who immigrated before 1800, and many after that in varying locations. I was making a list of those before 1800.

No guarantees as to the accuracy of my extractions or notes. The opportunity for errors is great. But, I do not think most of these immigrants are in Gilbert Cope's project. I could see trying to match some of them against my Pennsylvania 1850 file, etc.; especially those who came in after 1800. ,
