Note 1633 — Chapter VII · RICHARD AND ENGLAND. 1189–1194.

Frederic’s father and Leopold’s father were half-brothers, sons of the two marriages of Agnes of Franconia, daughter of the Emperor Henry IV. Conrad’s mother, Judith, was a child of Agnes’s second marriage with Leopold, marquis of Austria. Conrad’s father was the Marquis William of Montferrat who had been one of Henry II.’s allies in his struggle with the Pope (see above, p. 60); and his elder brother had been the first husband of Queen Sibyl. On his own iniquitous marriage, if marriage it is to be called, with her half-sister and heiress, Isabel—an affair which seems to have actually broken the heart of Archbishop Baldwin of Canterbury—see Itin. Reg. Ric. (Stubbs), pp. 119–124; Expugn. Terræ Sanctæ (Stevenson, R. Coggeshall), p. 256; Gesta Ric. (Stubbs), p. 141; Rog. Howden (Stubbs), vol. iii. pp. 70, 71. Conrad’s antecedents are told by Rog. Howden (Stubbs), vol. ii. pp. 320, 321. Considering, however, the case of Guy of Lusignan, it is perhaps hardly safe to admit a charge of homicide against any claimant to the throne of Palestine on Roger’s sole authority.
