Evidence for dynastic succession among early Celtic elites

[Riverman]

Matrilineal dynasties?
Interesting. Always thought IEs were very Patriarchal cultures.

If they find a matrilinear connection between elites in different regions, this might primarily point to these elite women marrying in between these centres of power. On the other hand, if they could prove that three generations had the same mtDNA, but different yDNA each, they might have a point.
I doubt the latter is the case. Consider how many of the big European aristocratic lineages had or still have female Habsburg DNA. That doesn't mean all those houses were materilinear...
