Let's do 'a little' mathematical calculation ... based on the slim chance of the present Queen reaching her mother's age without abdicating.

Meaning that ... between 2028 and the advent of the 22nd Century will be ruled, in turn, by:
Charles III, William V and George VII, respectively.

Always assuming, of course, that neither of the three in line of succession choose to reign using Christian names other than the ones they've been given.
