That's a pretty interesting list! A lot of interesting entries there, including a couple (e.g. Needlemakers) signed by Cromwell.

Given that it was issued by the privy counsel it is interesting that it has some notable omissions (though how comprehensive can the records be over such a long period, anyway?). I thought at first it might have been limited to charters in the current UK, but it does have the Massachusetts Company (1629), though not Virginia's charter (1606). Has the East and West India Companies, but not the College of William and Mary (1693) -- there are images of that one on the web, though not the signature.

My school was also in the Massachusetts colony, the somewhat pompous Roxbury Latin, 1643, charter 1645 (the unfortunate Charles I). It's been more than 40 years since I clapped eyes on its charter - astonishing they haven't put it online. My memory that it was 1640 was corrected by a bit of web searching.

Really these things are archaic silly relics, like monarchies themselves.
