Hey Brandon! Those dates line up with what I have. I obviously misspelled the Henrie and your spelling would be more appropriate given the premise that our Pettit's came to England from France, probably during the Norman Invasion. I have a rental car for one day in London and will make this my mission for that day. I'll report back what I find. This is going to be a real ancestry trip for me. I'm already planning to see a date stone in Scotland with my 7xGGparents initials from 1691. We're also going to Paris, so if anyone has information on any family related people or places there, they can send them to me and I'll make an effort. We don't have a rental car in Paris, so we'll be limited in travel.
By the way, I have made contact with the daughter of Roger Birch who owns the property in Cow Pens where the Pettit cemetery is located. Had to do some detective work but she gave me his number and invited me to call him. I haven't yet, but will soon. I'd like to go up there in late May.
Thanks again for the info.
