In shortness... from Æthelred-Elizabeth II (Not looking at any books here, and in Coincraft abbreviation from William I onwards)... Æthelred II, Canute, Harold I, Harthacnut, Edward the Confessor, Harold II, W1, W2, H1, ST/MT, H2, R1, JN, H3, E1, E2, E3, R2, H4, H5, H6, E4, H6, E4, E5, R3, H7, H8, E6, Lady Jane Grey, M1, EL, J1, C1, Commonwealth, C2, J2, WM, W3, AN, G1, G2, G3, G4, W4, Vicky, E7, G5, E8, G6, EZ... It's that simple, i canm even do it with pretty accurate dates. Scottish kings are funnier... (others before like Roberts I-III, and i'm sure there's a David in there) then from about 1406 James I (died in his slippers), James II (Blown up by his own cannon), James III (murdered by a 'monk'), James IV (died at Flodden), James V (Died shortly after a battle, i think...), Mary (got the chop, many times), James VI, Charles I (also got the chop) etc.
