[3] A metrical epitaph, preserved by Rudborne, claims for him a descent from Charlemagne, which implies that he, like Walter's wife, was 'de sublimi prosapia Gifardorum' (see p. [355] supra).

[5] Old Monasticon, i. 245b; and vide infra, p. 393. A curious sketch of the above scene in a MS. of Henry of Huntingdon (Arundel MS. 148) depicts Baldwin with two of the Clare chevrons on his shield, and a marginal note, almost illegible, duly describes him as grandfather of Baldwin Wac. This sketch is overlooked in the British Museum catalogue of drawings.

These were the first and second known bearers of the name. The latter occurs in a St Riquier charter of 1058. Poix was some fifteen miles from Amiens, and its lordship was of considerable importance. A charter of 1030 to Rouen Cathedral is said to contain the name 'Galtero Tyrello, domino de Piceio'.
