Reasons why any man with an R1b haplotype needs to take the deepest test he can afford, to determine exactly which "flavor" he belongs to!
Specifically, R1b-DF98 is Prince Philip's haplotype, the crown having passed through the female line several times (most recently through Queen Elizabeth II). His line traces back though Schleswig-Holstein to the Oldenburgs - the upper reaches look highly suspicious, as some of the pre-Oldenburg names are fart jokes.
Elizabeth II's male ancestry runs through Saxe-Coburg-Gotha - Prince Albert of same having married into the Hanover royal line (Queen Victoria) - and back to the House of Wettin (Y-DNA signature characterized as Haplogroup R1b-U106 with the additional SNP Z305+).
No known and confirmed Hanovers have volunteered for testing, so far. The odds favor their being yet another R1b variant.
The first of the Hanovers, George I, inherited his right to the throne via his mother, the Electress Sophia, a distaff descendant of James VI/I of Great Britain.
The Stuart Y-DNA signature has been confirmed (several times over) as R1b-L21 with the key SNP mutation L745. (This is a "Celtic" flavor.)
The Tudors having daughtered out with a vengeance by 1603, their Y-DNA signature is unconfirmed.
The Plantagenet Y-haplotype is most likely G, details not quite certain at this time. (aDNA taken from the remains of Richard III, not in optimal condition after 500+ years).
Everyone is still guessing about the Norman Y-haplotype, with the odds (as always) favoring some version of R1b.
