Research Notes:
coheiress of her father [Ref: Richardson RoyalAnc v5p301]

1230: coheiress to her father; inherited a 1/4 share of a 1/3 share of the barony of Miles of Gloucester [Ref: Richardson RoyalAnc v5p301]

inherited Barony of Builth from father [Ref: Sanders Baronies p8]

1233: coheiress to her great uncle, William Briwerre [Ref: Richardson RoyalAnc v5p301]

inherited 1/20 Barony of Horsley from William de Briwerre d.1233 [Ref: Sanders Baronies p123]

When William de Braose was executed by Llewelyn in 1230, the English crown assumed control of his lands, among them the lordship of Builth. Isabel tried to obtain seizin of Builth, but her efforts were in vain [Ref: Sanders Baronies p22]

1246: after death of her husband, she was forced to be satisfied with Haverfordwest; lordship of Builth continued in the hands of the crown [Ref: Sanders Baronies p22]

NCP 6 462-63 note (n) states that Isabella married secondly Piers FitzHerbert (see AR, line 262), but this seems to be not only false but impossible. See Walter Lee Sheppard, Jr., "Three Generations from Henry fitz Roger", National Genealogical Society Quarterly 59-254-62 (1971) at 256, 60:25-35 (1972) at 26, though his statement that Piers was alive in 1248 is in error; Piers died between 19 May and 6 June 1235, NCP 5-465 note (d) and could not have married the widow of Dafydd, who died in 1246. Vernon M. Norr, Some Early English Pedigrees (Arlington, Va., 1968), p. 35, attempts to salvage this marriage by showing Piers as first husband and Dafydd as second, but this is equally impossible, since Isabella married Dafydd in 1230 and Piers died in 1235.
