Per A History of the Holland Family:

Robert de Holland probably died about this time, as his son Thurstan represented the family on the important inquiry held in 1242-43 to ascertain the knight's fees in the Hundred of West Derby chargeable to the Gascon Scutage. The name of Robert's wife is not known, but he had a large family, among whom were Thurstan, his son and heir, already mentioned, Adam, frcmi whom sprang the Hollands of Euxton, Richard, from whom descended the Hollands of Sutton, Matthew, Robert, and Roger.^

Under Thurstan de Holland the family seems to have prospered, and on all hands we find Hollands acquiring estates and holding important offices. As has just been ^ Assize Rolls, 404, Lane ; Roger and Adam.*

He married, secondly, Juliana, a daughter of John Gellibrand, and had four other sons, Thurstan, Adam, Elias, and Simon. To this last he gave lands in Pemberton, Wigan, and Golboume.'

He is said to have married, thirdly, a daughter of Henry de Hale, an illegitimate son of Richard de Meath, Lord of Hale. The evidence of this is not very satisfactory... [and it appears that Hale came into the Holland family through Thurston's mother's mother].

Thurstan, who, as we have already seen, was of man's estate in 1241, and who was probably bom about 1210, lived to a good age, and witnessed a deed as bailiff of Makerfield in 1386.^ He must have died shortly after this date; he was certainly dead in 1293. In witnessing a charter to Stanlaw Abbey in 1272 he is described as Sir Thurstan de Holland.
