The Blackledge/Blacklidge DNA Project adds an additional tool for genealogical research. We know the ancestors of over 90% of Blackledges in America come from three major lines, all with Anglo-Saxon connections. We are comparing data to validate the American relationships and hopefully establish the English connections. (Prehistory and Origins of the Blackledge / Blacklidge Families of Blackley) R1b‑BY56073 — William Blackledge the Tanner's Lineage (Blackley Hamlet) Origins in the Late Bronze Age Copper from the Hallstatt cultural sphere circulated widely across Europe and reached the Atlantic tin regions of Armorica (Brittany) and Cornwall, where bronze production depended on tin. The ancestral branch R1b‑FGC36903 likely moved from the Hallstatt zone into Armorica between 850–750 BCE, where it formed the downstream lineage R‑FGC48672. The German R1b‑FGC48672 Question One tester in Bavaria belongs to R1b‑FGC48672 but is negative for downstream R1b-BY3965 and R1b-FTC46410. Because this German sample stands alone among more than eighty British FGC48672+ men, and because it sits upstream of the British branch, it is not yet possible to determine whether he represents: • a British medieval mercenary who settled in Bavaria, or • a continental Hallstatt‑era branch that remained in Central Europe. With only one continental sample, the evidence is insufficient to draw conclusions. Additional testers from Germany, Austria, and Switzerland will be needed to clarify whether R1b‑FGC48672 had a surviving Hallstatt‑era presence on the continent. At present, both R‑BY3965 and R-FTC46410 are exclusively British for ~2,800 years, supporting an Armorican → British migration during the Late Bronze Age / Early Iron Age. --- (Armorican Bronze Age Context) Côtes‑d’Armor: The Only Region With Production Debris Côtes‑d’Armor is the only Armorican region with evidence of bronze production waste, including: • unfinished bracelets • miscasts • casting flaws • scrap bronze These finds come from the Kerouarn (Kerouarch) Hoard, a ritual‑workshop enclosure dating to the Atlantic Middle Bronze Age. Other hoards in Côtes‑d’Armor — Saint‑Brandan, Tréglamus, and Plélauff — are ritual deposits but do not contain production waste. Other Armorican Hoards Additional hoards across Armorica reflect the wider Atlantic Bronze Age metal network: • Quimperlé axes (Finistère) • Vannes socketed tools (Morbihan) • Caen spearheads (Normandy) These show Armorica’s integration into the Atlantic exchange system linking Brittany, Britain, and Ireland. Movement Into Britain During the Late Bronze Age and Early Iron Age, Armorica and Britain formed a shared Atlantic cultural and genetic zone. People, metal, and ideas moved across the Channel over many centuries, contributing to the ancestry of Iron Age Britons. This was not a single migration event but a long‑term exchange system. --- Blackley in the Roman and Early Medieval Periods Roman Era Mamucium (Manchester) was garrisoned by Roman auxiliaries who mixed with the local Brigantes, as shown by Brittonic pottery found in the fort.The civilian settlement (vicus) contained multiple furnaces and smithy workshops, forming one of the earliest industrial zones in Manchester. Collapse of Roman Industry When the Roman army withdrew from Britain in 410 CE, the industrial economy centered on forts like Mamucium collapsed. Roman smithies, which had supplied the military with tools, fittings, and repairs, were abandoned. Skilled metalworkers in rural Brigantian territory suddenly lost their largest patron. As a result, the Mamucium shifted to agricultural use. Nennius’ Historia Brittonum (c. 830) lists a city called Cair Maunguid, which some scholars associate with the Manchester region. (Shift Toward Cattle and Woodland Crafts) In the centuries that followed, the economy of the Manchester region reorganized around: ~Cattle herding ~Woodland management ~Wetland resource use ~Local craft production The Irk Valley, including the slopes just south of Blackley, offered ideal conditions for these activities: oak woodland (tannin source), clay soils, streams, and pasture. Families with a background in metalworking often shifted into cattle‑based crafts, including hide curing and early tanning, because the skills overlapped: furnace → pit construction charcoal → bark processing quenching → soaking and washing workshop → yard‑based craft space This transition is well‑documented across post‑Roman Britain. (Earliest Evidence of Tanning in the Manchester Region) Archaeology shows that tanning in the Manchester area becomes visible only in the medieval period, not during Roman rule. Excavations in the city center reveal: ~Tanning pits ~Bark‑lined vats ~Hoof and horn waste ~Leather off-cuts These date to 1200s–1400s CE. Blackley itself has no excavated tanning pits, but manorial records from the 1400s list tanners working along the Black Leach and Irk tributaries. This is the earliest documentary evidence of hereditary tanning in the Blackley hamlet. (Anglo‑Saxon Period) By the early 7th century, the area likely experienced conflict during the expansion of King Edwin of Northumbria. Anglian settlers established themselves in the region, calling the hamlet Blæclēah (“dark clearing”), the origin of modern Blackley. --- (I1‑BY64729 — John Blackleach’s Lineage in Blackley Hamlet) (Norse‑Gaelic Origins) During the Viking Age, Norse‑Gaels settled in Blæclēah and assimilated into the local population. One I1 lineage, ancestral to I‑FTA75343, originated in eastern Götaland, Sweden and entered the Norse‑Gaelic world. This lineage later split into two branches: • I‑FTA75343 (no BY69981) — a branch that assimilated into the Clan McGlynn sept of Donegal • I‑FTA75343‑BY69981 — the branch that migrated into the Manchester region and became the direct paternal line of John Blackleach (1605–1683) This makes the Blackleach family a Norse‑Gaelic paternal lineage with Scandinavian origins and later integration into the Gaelic world before settling in medieval Blackley.
