I've recently been looking at the Swynnerton family of Staffordshire, who were pretty well documented by one Canon Bridgeman. While doing general searches on the National Archives website I came across this http://discovery.nationalarchives.gov.uk/details/r/C6553377. Now, John son of John d.1408, proved his age in 1429, so that is one of the John's involved. But he died the following year and his successor was his uncle Thomas. There is no cousin John in the pedigrees I've looked at. So, now I have a bit of a mystery. Would this document be likely to have anything that might help explain this? Or is this just going to be another case of a scribe with too many Johns?
