Hammon III de Massey - First name is Hamon

Spelling was optional, back then, and the same name might be spelled several different ways. "Hammon" is one of the less likely ones, but I still would not be surprised to find it occasionally.

More common even than "Hamon", especially the earlier you go, is "Hamo". Various charters and other legal documents have been found with this form. http://discovery.nationalarchives.gov.uk/details/r/C9544520 (c. 1329)

I was a little confused by this one because Pamela says "One N" when the name already has one N. I suspect she meant one M ;)

And by the way, Pamela, if you're going to be the spelling police, you need to make sure YOU don't make any errors. It's "ChesHire", not "Chesire".

I was emphasizing the spelling error *you* made. You spelled it "Chesire", *without* the H. It's "Cheshire".

I suggest you resign from the Spelling Police.
