Maciamo can you list your sources for all this info?
BTW - some new info:
Y-DNA of Richard III was G2:Richard III (1452-1485) => J1c2c (mtDNA)
And here is the comment:
"P287; Differs from that of three male line descendants of Edward III via John of Gaunt, Duke of Lancaster and Henry Somerset, 5th Duke of Beaufort (1744–1803), which are U152 xL2,Z36,Z56,M126,M160,Z192. Infidelity must therefore have taken place somewhere on either the York or Lancester lines."
