My grandmother is related to 9,000 year old Cheddar Man(U5a)
My yDNA (R1b) has been in Europe at least 25k...possibly 45k years.
R1b is presently the largest European yDNA haplogroup. 'H' is the female equilivent.(mtDNA)
But then they wouldn’t have been Indo-Europeans (Aryans) — and that R1b is most common in Western Europe, not Eastern Europe which has the haplogroup R1a more in common (just like Indians and Iranis). But that is an interesting point. Perhaps western Europeans have partial non-ARyanic descent?
