So then I find a reference to one Hugh Calveley's being a great nephew to the famous Hugh Calveley, instead of the son, but I couldn't find anything else out. Then I somehow stumbled on Google Books and found this, which is a full listing of the proper genealogy. Now I just have to convert the dates. 11 Henry VI is apparently 1432-3, which fits the genealogy I have now.
Whew!
On edit: I can't figure out what date 10 Henry VII is. Any help would be appreciated.
