I know this is boring to you all but forgive me .... I am excited by it.
Today I found no fewer than 6 ancestors who fought with Henry V at Agincourt .... from which two were knighted by the King.
Now that is the point of family history to me.
Anyone who thinks they may have had ancestors at Agincourt (on the English side) there is a fantastic bit of research done by the Universities of Southampton and Reading that lists all of the English side. They have, apparently, culled the information from the paylists maintained by the King's servants to ensure that wages were accounted for. You can search by name, rank etc.
