DNA Over Deeds (With Charters): E-BY5775 Linking Colquhoun, Kilpatrick & McCarter By Tiffany McCarter Evans — The Lennox Chronicles Plain-English takeaway: We match Y-DNA breadcrumbs (E-BY5775 and daughter branches) with page-cited medieval charters . When documents and DNA point the same direction, we build testable working theories —and we show our receipts so anyone can follow. What we’re doing (no jargon, promise) Y-DNA passes down the direct father-to-son line. Every so often it picks up a tiny mutation—call it a breadcrumb. Scientists give each breadcrumb a name (a SNP ). If a group of men share the same SNP, they usually share a distant paternal ancestor. Our project follows one breadcrumb cluster in the Lennox: E-BY5775 . We put charters (land grants, witness lists, place-names) beside modern Big Y-700 results . Where both sets of evidence agree, we have a testable working theory . Where they disagree, we adjust. That’s “ DNA Over Deeds—But Not Without Charters...
