Thank you for your response.
Yes, I have accessed John Grenham’s page and worked through the 925 Ford’s. The I’ve also worked through Griffith’s valuation rolls.
No I have not done a DNA test. For one thing I’m not sure how such test can connect back 200 years and the other reason is far more sinister. The US Security forces have a issued a warrant on Ancestry, and no doubt other genealogical websites, in order to obtain all the DNA data on record. The matter is before the US courts.
