When William III was born, he wasn’t in the line of succession at all, since there was no king at the time. When the monarchy was restored, he was probably pretty far back: his wife, Mary, was ahead of him in succession when the two of them were made joint rulers.
But probably the furthest from the thone was Henry VII. He wasn’t even the legitimate Lancastrian claimant by birth (though he claimed the role). When he was born in 1457, his connection to the throne was tenuous as possible: he was the king’s father’s widow’s grandson. They both were related through John of Gaunt, who was his several times great grandfather. And that doesn’t include the Yorkist claim (which did have some legitimacy if you followed strict promogeniture).

Good call on Henry VII. Although he could have taken an anachronistic precedent from William and Mary, as his wife was the Yorkist heiress after Richard III’s death (barring Richard’s story about Edward IV’s bigamy making all his kids illegitimate). This was Philip II’s (the Philip II, of Spanish Armada fame) claim to the throne – he was Mary I’s husband, and “due the throne by the crown matrimonial.”
William III, however, requires a bit of clarification. He was in fact not that far removed in succession. First, going on the pretendership theory that the heir apparent or presumptive accedes when the reigning monarch is overthrown and executed, Charles II would be the “king of record,” even though the only pieces of the realm to recognize him were the Channel Islands and Virginia. In 1650, when the future William III was born, the line of succession after the de jure and future Charles II would have been:
- Prince James, brother of the King, later James II
- Princess Mary, Princess Consort of Orange, eldest sister of the King
- Her son William, the future William III
…
On January 1, 1688, prior to the birth of the Old Pretender, the line of succession from James II was:
- Princess Mary, Princess Consort of Orange, the King’s elder daughter
- Princess Anne, the King’s younger daughter
- William, Prince of Orange, the future William III, nephew of the King and son of his late eldest sister
…
If Mary had acceded alone after the Glorious Revolution in 1689, the succession would have been Anne, her infant son Prince William, and William of Orange, with William twice briefly bumped to fourth place by Anne’s babies Mary and George, who were born and died in infancy in 1690 and 1692 respectively. Anne herself would have succeeded on Mary’s death in 1694, instead of Wlliam reigning alone as he did. From Prince William’s death at age 11 in 1700 until William of Orange’s own death in 1702, he would have been heir presumptive in his own right.
So all things considered he was not that far removed.
