NOTES
"Thomas Ridley and William Girlyngton"
Both recent mayors, these men were the representatives of York at 
parliament;  it made sense that they would be mandated to negotiate for 
a new charter while in London  in fact, they may have been selected 
for parliament because it was desired to send leading townsmen 
to obtain the charter. 
"John Shirwod"
It was common at this period to employ the town clerk on this type of 
business since it required someone trustworthy and capable, with legal 
ability.  John Shirwood is usually stated (without authority) as having 
been appointed to that post in February 1442, but I suspect he may have 
held it since 1437.  He remained in the post almost continuously until 
1470.
"Peter Erden"
Peter Erden, or Arden, was one of the lawyers retained annually by the city.
"Nicholas Girlyngton"
Girlyngton was one of the city lawyers from the mid-1450s into the 1460s. 
Likely a relative of William Girlyngton, at the time of the above document 
he may conceivably have been apprenticing in the law in London.
"James Hopwod"
Hopwood was perhaps a London-based lawyer.
"Cardinal of York"
York's archbishop, John Kempe, had been appointed a cardinal in 1439.
