There are two contemporaries called Henry of Guildford: Henry Gerard of Guildford (who was a clerk of John de Lovetot) and Henry Marshall of Guildford (who was a clerk of Solomon of Rochester and later a Common Bench justice), and they are not always adequately distinguished in contemporary sources. Fortunately it is possible to be certain that the man who appears in your list is Henry Gerard of Guildford, for in Hilary term 1294 he sued the abbot of Bury for twenty marks arrears of this very annuity of four marks a year which had been granted to him by the abbot at 12 kal. February 12 Edw. I (21 January 1284) at Culford: TNA, CP 40/103, m. 127d. His connexion with John de Lovetot went back to at least 1276 and he was chosen as an auditor by John’s executors in 1296; he had previously been a clerk of master Richard of Staines. He was convicted of misconduct while in Lovetot’s service and imprisoned in the Tower in 1290 but was ransomed for 100 marks.

Henry de Schineholt was a clerk in the service of Solomon of Rochester, the senior justice of the ‘southern’ eyre circuit of the eyre, from 1281 onwards (and there is a reference in a complaint about him at 1287 Hertfordshire eyre which shows him writing a plea roll there at the dictation of his senior colleague, Robert of Preston), but after Rochester’s disgrace in 1290 he passed into the service of his successor as senior justice of that circuit, John of Berwick, in whose service he is still to be found at the time of the 1299 Cambridgeshire eyre. I think the name may be derived from a place name in Buckinghamshire (he is stated to have been from Shenholt in Bucks in a Kent assize of 1203: TNA, JUST 1/1323, m. 43) but I have not found it in the English Place Name Society volume.
