My question literally begins in the Tudor era and runs to the Stuarts. My 10th gr-grandfather Robert Barham was appointed as Comptroller of the Pipe Roll, an Exchequer office, in 1596. Sources show him still in that position as late as 10 years later, though after that, I've no proof. The problem is the lack of any enumerations of office holders for that position, at least that I've been able to locate. Was this a lifetime appointment? He is known to have died in late 1630, which would mean 34 years of service in this capacity. He was in his 20s when first appointed, so it's not impossible.
I've seen several calendars of appointments for Wardrobe and Royal Household positions, but Exchequer, including Comptroller of the Pipe Roll, remains elusive. Can anyone help?
