The House of Windsor's claim to the British crown is a Stuart one (just as the Stuarts' claim was a Tudor one) - it may be a bit (or even extremely) tenuous but it comes through Elizabeth Stuart (sister of K. Charles I) who married Frederick V the Kurfuerst (Elector) of the Pfalz (Palatine), and their daughter Sophia (who married Ernest Augustus Elector of Hannover) was the mother of K. George I - the nearest Protestant claimant to the British crown after the death of Q. Anne ("the last Stuart monarch"). Incidentally his son, K. George II, was the last British ruler to lead his troops in battle (at Dettingen).

Q. Victoria was K. George II's great-granddaughter, and K. George V was her grandson.
