These confirm that skeletal remains from the royal crypts in Płock Cathedral—likely belonging to Duke Władysław I Herman і Bolesław III Wrymouth—have been sequenced. The discoveries reveal a shared Y‑chromosome lineage traced to the ancient Picts of Scotland, based on high-quality genetic matches.
🧬 Genetic Findings: A Celtic Royal Line
-
The analyzed remains belong to the rare R‑L1335 haplogroup (full label: R1b1a1b1a1a2c1a1f), found in 30 men and 3 women—most of the males shared this Y-chromosome signature Colombia One News and archeology.org.

Comparative DNA analysis linked them with an unnamed Pictish male from a 5th–6th century Scottish burial (Balintore, Easter Ross)—currently the oldest known Pict male DNA sequenced archealogy Magazine.
🧭 Broader Haplogroup Context: R‑M269 & European Royalty
The male Piasts’ lineage, R‑L1335, is a branch of R‑L21 under R‑P312, itself derived from R‑M269—the dominant Western European paternal haplogroup. Other major branches include:
-
R‑Z381: Belonging to the U106 branch, this haplogroup appears in Germanic/Frankish dynasties like the Merovingians and Bourbons, as detailed in this genealogy: Franks, Genealogy, Belgian-Dutch Goths.
-
R‑L1335: The Piast-associated line under L21—a typical marker of Celtic populations across Scotland, Ireland, and Wales.
These two lines are parallel descendants of R‑M269, diverging thousands of years ago into distinct noble genealogies.
📜 Authenticating Royal Context in Płock
-
Remains came from the confirmed royal burials in Płock Cathedral, including those of Władysław I Herman і Bolesław III, forming the largest Piast necropolis gazeta.pl.
-
The homogeneous nature of the Y-DNA among male remains confirms a patrilineal dynasty, not isolated anomalies .
🏴 Celtic Connections: Verified Lineage Matches
Several documented Celtic individuals share the R‑L1335 haplogroup, linking the Piasts to other noble lines:
-
Unnamed Pictish male (Balintore, 5th–6th c.)—earliest known sample in this lineage .
-
Alasdair MacGregor of Glenstrae (16th-century chief of Clan Gregor), whose descendants in FTDNA records show R‑L1335 matches .
-
Leading chieftain lines in clans like Chattan and MacKinnon also exhibit proximity to R‑L1335 or parallel L21 subclades.
These findings position R‑L1335 as the oldest surviving royal haplogroup from the Pictish elite, reinforcing the Celtic origin theory for Piast male ancestry.
🛡️ Dynastic Line to Galicia, Kievan Rus, and the House of Brunswick
This Celtic-identified Piast royal lineage connects directly to later dynastic lines of Galicia–Volhynia, Kievan Rus, and ultimately the House of Wolfenbüttel-Brunswick, through intermarriages and succession. As documented in the article Succession in the Kingdom of Galicia, Lodomeira, and Lviv, the genealogy unfolds as follows:
This not only illustrates the continuous royal bloodline from Bolesław III into the noble houses of Germany, Galicia, and Eastern Europe, but also underscores the fact that this Piast-linked dynasty ruled in Kiev, aligning with broader Norse-Gaelic and Celtic ecclesiastical activity in the region.
🕊️ This further corroborates the historical evidence presented in the companion article from St. Andrew’s OCC:

This connection strengthens the case for Celtic ecclesiastical and dynastic continuity reaching deep into the heart of Eastern Christendom.
🌍 Historical Significance & Heritage Unity
These revelations redefine historical narratives: the Piasts were not solely Slavic or Viking but innately Celtic in their paternal ancestry. The discovery of the oldest-known Pictish male lineage in Poland’s dynastic origins:
-
Forges a deep ancestral link between medieval Poland and the Celtic realms.
-
Opens doors for individuals with Polish-Scottish heritage to embrace a shared royal lineage.
-
Clarifies that medieval dynasties often encompassed diverse, non-centric roots—a counterpoint to narrow nationalisms.
In summary, the Piasts carried the R‑L1335 haplogroup, linking them to the ancient Pictish elite, and marking the earliest recorded Pictish male lineage in Europe—now traced to Płock. Their Celtic royal roots, shared with notable ancient and medieval figures, challenge and enrich our understanding of early European dynastic history.
