` ::I agree with listing the Commonwealth in the succession table for the Monarchy. However, it is not usual to regatrd peerages as falling into abeyance during the Commonwealth, and I think Charles II should be shown as immediately succeeding to the Dukedom of Rothesay. ::The position of Prince of Wales is more tricky: that title is not passed in ``succession`` in any case, so I'm not sure what sense it makes to call it ``vacant`` when no one happens to bear the title. No one bore it between 1625 and 1638, but it was not ``vacated`` by the Commonwealth like the monarchy was; and anyway, Charles I did not become Prince of Wales in immediate succession to Henry Frederick, so logically that ought to be a ``Vacancy`` as well.   `
