The Strothers were an ancient Northumbrian family, which by the early fifteenth century had established connexions to some of the leading families of the region (such as the Swinburnes, Musgraves and the Blenkinsops) as well as to the borough of Newcastle-upon-Tyne (where Strothers had served as mayors and MPs since the mid-fourteenth century). Indeed, our MP’s brother, John, who had unexpectedly inherited the family estates on the childless death of his nephew, William, in 1415 or 1416, represented that borough in three Parliaments between 1417 and May 1421. Strother’s own prospects were to be enhanced in similar circumstances, for John himself died childless in March 1424.
None the less, whatever the burdens upon Strother’s inheritance, it was enough to give him a place in local affairs, particularly because Agnes appears to have alienated to him her interest in Wallington, which, according to the subsidy returns of 1428, was then in his possession, and also part of her dower property. Indeed, in the subsidy returns of 1436 he was assessed on a respectable income of £20 p.a. , a worthwhile sum in the impoverished far north.
As escheator, Strother played a part in the causa de Heron, the famous dispute between two Northumberland families, the Herons of Ford and the Manners of Etal. This resulted in the murder of William Heron in January 1428 at the hands of John Manners†. In the following June an inquisition held before Strother falsely found that Heron had died seised of his lands in Northumberland, thus bringing his lands into royal wardship to the detriment of the interests of Heron’s widow, Isabel. She complained that this finding was procured by Manners, and it may be that Strother was here guilty of partisanship. In any event, in April 1429 he was nominated by Manners to act as an arbiter in the matter on his behalf.
In November 1430 Strother’s long stint as escheator finally came to an end with the nomination of another lawyer, John Cartington*.
