Simeon of Durham names "Dolfin, Walther and Cospatric" as the sons of Gospatrick. He is named second of the three sons of Gospatrick given by Roger of Hoveden. A memorandum dated to [1275] records that "Earl Cospatryk formerly earl of Dunbar in Scotland had a brother Dolfin earl of Northumbarland…both…bastards", that they had "a legitimate brother Waldeve and a legitimate sister Etheldreda…of one father and one mother". It seems unlikely that Waltheof was his father’s legitimate son as his father’s earldom was transmitted to his son Gospatrick. The Cronicon Cumbriæ records that “Ranulphus de Meschines” enfeoffed “Waldevum filium Cospatricii de Dunbar comitem in Scotia” with “tota baronia de Allerdale” and that “Willielmus de Meschines dominus de Coupland” enfeoffed “Waldevum filium Cospatricii” with “tota terra inter Cocar et Derwent”. "…Cospatric frater Dalfin, Waldef frater suus…" witnessed inquisitions by "David…Cumbrensis regionis princeps", dated 1124, concerning land owned by the church of Glasgow.
Lord of Allerdale. Abbot of Crowland [1126] to Dec 1138, when he was deposed at the legatine council of Westminster. An undated agreement between Geoffrey abbot of St Albans and "Gospatric the earl" recites that the abbot granted Gospatric and "his son Adam (…formerly called Waldief)" the "land of Archil Morel…Beuuicke". “Waldevus filius Cospatrici comitis” donated property to Gysburn Priory, with the consent of “uxore mea Sigrida et filiis meis Cospatrico et Alano”, by undated charter which names “El. filio Erlafi presbyteri cognate meo”. A charter of King Henry II records donations to York St Mary, including the donation of “villam de Stainburn” by “Walthef filius Gospatrici” and "villam de Saltergh et…de Whyrkingtona" by "Gospatricius filius eorundem". 1
