I'm rather late in responding, but the passenger list to which you refer named a "Peter Atterborn," I believe. But there are also published sources which say that the "Constance," which was bound for Virginia, never sailed due to repairs and court claims. Another published source shows "Peter Atterborne" in New England, which must indicate he later made passage--probably on a different vessel and to a different port. This information (with sources cited) can be found in the original "The Arterburn Cousins" book, and also at the Arterburn DNA Project. Hope this helps!
