Hi
Looks like similar info that I have found on the web re the family. I will need to confirm my connection. I have a marriage record of George Woodfield (my ancester???) marriage to Suzanna Batt 24th october 1779 in Cheshunt, daughter of Danzick Batt , who was the son of Danzick Batt Bab 25.3.1702.
I also have found a Daniel Batt bab 18-1-1740, ? your Isaac's brother, but not any more regarding these families as yet.
You do notlive in England I can assume?
When I get around to doing some more local research to verify my connection (ie the marriage by banns for George & Suzanna dont actually say who the parents were,-but I think with the name Danzick it must be quite rare. I have not found any more) if you want to know more , I would be able to let you know. I dont live in Hertfordshire but would venture down sometime or get the county archives to have a look.
Thanks for getting in touch anyway
