General Notes

William Daubigny (by first wife Margery Umffreville), d. 1242, Lord of Belvoir; m. (1) Albreda Biset; m. (2) Isabel, b. 1233/5, living 1285. [Magna Charta Sureties]

Note: MCS states that William's daughter Isabel is by his second wife Isabel.  Obviously the birth date "1233/5" above is wrong, because Isabel would have only been 9 (at the most) when William died.  The birth date would more likely be the daughter Isabel's birth date.

----------------------------

William de Albini, feudal Lord of Belvoir, like his father, adhered firmly to King Henry III. He m. 1st, Albreda, dau. of Henry Lord Biseth, and 2ndly, Isabel-----, and left issue by the former, an only dau. and heiress, Isabel de Albini, who m. Robert de Ros, Lord Ros of Hamlake, and conveyed to him the feudal barony and castle of Belvoir, which eventually passed from the family of Ros to that of Manners. [Sir Bernard Burke, Dormant, Abeyant, Forfeited and Extinct Peerages, Burke's Peerage, Ltd., London, England, 1883, p. 160, Daubeney, Barons Daubeney, Earl of Bridgewater]

Note: Magna Charta Sureties states that Isabel was daughter of his 2nd wife Isabel.
