The Sunghir burial

Josip007

The Sunghir burial was discovered on the northeast outskirts of Vladimir, Russia, and excavated between 1957 to 1977.
The two boys, roughly 10 and 12 years old, had “physical conditions,” yet they were buried “head to head in a long, slender grave with 10,000 mammoth ivory beads, 20 armbands, about 300 pierced fox teeth, 16 ivory mammoth spears, carved artwork, deer antlers and two human fibulas (calf bones) laid across the boys' chests".

A sad ending for the boys

Phylogenetic
analyses of the Y chromosome sequences place
all Sunghir individuals in an early divergent lineage
of haplogroup C1a2 (fig. S8 and tables S12
to S15). Y chromosome haplogroup C1, which is
rare among contemporary Eurasians, has been
found in other early European individuals, including
the ~36,000-year-old Kostenki 14 (11)

Y-DNA Haplogroup C, is also the haplogroup that 'Cheddar Man' and 'La Brana 1' (NW Spain 7k years old) belong to. It's most commonly seen these days in Australian aboriginals, Northern Asians (Mongolians in particular) and in certain Amerindian populations.

I seem to remember reading that C pops up under some Scottish named like Armstrong or Elliott.
One idea was that it is a sub group associated with Southern Eurasia and Roman legions were the source.
