More can be added to the earlier biography.
Crackenthorpe’s principal patron in the early part of his career was John, Lord Clifford, who appointed him as his deputy as sheriff of Westmorland.
As noted in the earlier biography, the last years of Crackenthorpe’s career were seriously disturbed by violent resistance to his attempts to make good his wife’s claim to her share of the Lancaster lands. It is an open question whether these attempts were justified. At the time of their marriage his wife had not been coheiress-presumptive to the Lancaster estates; and there is no reason to suppose that her father contravened any marriage contract when, in 1425, after the death of his only son, he settled all his lands in Cumberland and Westmorland upon himself and his second wife, Katherine, in tail male, with remainders over to various male kinsman. None the less, Robert appears to have seen this settlement as a frustration of his legitimate expectations, and, in 1431, he secured the resettlement of the manor of Skirwith near Penrith (Cumberland), entailed in the male line in 1425, upon himself and his heirs.
Crackenthorpe, unwisely as it transpired, continued the offensive. In Easter 1437 he secured a writ of waiver against Katherine as Sir John Lancaster’s executrix for a debt of £40. More significantly, on the following 14 Oct., sitting as a j.p. at Kendal with Sir Thomas Strickland*, he took several indictments of felonious theft against John Lancaster; and, on 12 Feb. 1438, he sued out a royal commission of inquiry to the sheriff of Westmorland, his ally, (Sir) Thomas Parr*, on the grounds that the Lancasters had re-entered the manors recovered by the assize. This is the immediate context of the violence of the following summer. An inquiry held by Parr on 25 June found that the Lancasters were guilty of a second disseisin and awarded damages of £116 against them.
It is a fair speculation that it was this judgement that led the Lancasters to take the law into their own hands. On 25 Aug. they were joined by their allies, the Thornburghs, in murdering Crackenthorpe at Brampton near Appleby. At a session of the peace at Appleby on 11 Sept., held before Thomas, Lord Clifford, who had recently come of age, Sir Christopher Moresby† and Thomas Burgham*, a jury laid presentments against the murderers.
