Blennerhasset was from a leading Carlisle family with a tradition of parliamentary service. Another John had sat for the city twice in the early 1380s, and Ralph Blennerhasset represented it in the Parliament of 1413 (May). The family pedigree cannot be accurately constructed, but it is likely that Alan Blennerhasset, mayor of the city for several terms between 1370 and 1390 and perhaps the elder brother of the MP of the early 1380s, had three sons, namely Ralph (the MP of 1413), Robert, who was one of Alan’s executors, and John, who was probably the eldest son.
This John first appears in the records in 1420, when, in company with his putative uncle, Robert, he served as bailiff of Carlisle. Three years later, despite his youth, he was elected mayor.
None of Blennerhasset’s fellow citizens could match this record, and it is not therefore surprising that his mayoralty of 1423-4 was the first of many. On this evidence, he was long the most important citizen of Carlisle, and this is reflected in his frequent elections as mayor. Between 1429 and 1444 he is known to have served eight terms in the office, five of them consecutively between 1429 and 1434, and, since not all the city’s mayors can be discovered, there can be little doubt that he served more frequently both within and on either side of these dates.
Such perquisites of office were no doubt considered legitimate, but there is some indirect evidence that the dominance of the office by Blennerhasset and another citizen, William Denton, led to tension. This, at least is one interpretation of the city ordinance issued on 26 Oct. 1445. This was designed both to place a restraint on the mayor’s power by imposing upon him a permanent council of 11 and to set a limit to involvement in the mayor’s election by confining the franchise to a self-perpetuating group of 36, comprising the mayor, his council and 24 of their nominees.
The death of Blennerhasset’s mother, at a very advanced age, on 17 Mar. 1450 promised a further advancement in his status.
Another cause of potential conflict between Blennerhasset and the city were outstanding debts allegedly due by him and other members of his family. In August 1464, when the city’s accounts for the period 1458-63 were audited, he was found to owe 8s. as the arrears of the rent of a shop and a further £6 16s. 10d. on a bond he had entered into as long before as 1439. At the same time it was decreed in the city court that those refusing to render account to the corporation should be disenfranchised, probably an empty threat in the case of a family as prominent as his.
The other candidate as MP in 1442 was a merchant, at least so he is generally described in the records. The relationship between the two namesakes was a close one, and they were probably first cousins, although they may even have been brothers. They were of a similar age. When the two of them appeared as jurors in the proof of age taken at Carlisle in respect of another leading citizen, John Denton, on 19 June 1442, their ages were given as 52 and 50, although oddly the merchant, on this occasion styled ‘junior’ against the other’s ‘senior’, was erroneously said to be the elder.
The merchant’s next appearance in the records was also as a defendant: in 1463 Eleanor, widow of Ralph Dacre*, Lord Dacre, claimed £20 against him.
