This is the royal Stewart line, clearly you fit in. My point is that the R1b haplogroup though separated by thousands of years carries the same values on Y which means the ANCIENT line of Kings preceded both I-1 and R1b so likely a G or I ancestor in the first 40,000 years of Europe's recent history of the last 100,000 years.
Who that first person was? I certainly don't know, but we see evidence of the man in the Stewarts, and Romanov's Mt. Batten- Windsors. Possibly the Scandanavian Tutors, & Suttons who arrived from France after the Viking Incursion of 800 AD.
You have the distinct advantage as Justin says above of knowing that very specific bloodline over time. Congratulations, you are a rare person in the world as few of us know much about our Historical links to the past.

My Uncle Ernest Stevens, is the 11th GGrandson of Edward IV King and Brother of Richard III. But the male descent is perhaps different than Richards. There is reason to believe the descent through the Hilton line is still living but in a Branch of Rice Family which I do not have access.
