The Throckmorton Project is a Y dna project. Our goals are to establish Throckmorton/Throgmorton family Y chromosome signatures and their distinguishing Y signatures in lineages worldwide. This will expedite paper trail research. Two of our lineages have a common ancestor in Thomas Throckmorton 1412-1472. Some Mortons are Throckmortons. Please call Tom Howland 215-766-2126
