The Cranbrook data I have only goes up to 1812 on the discs- so you will need the GRO certifcates or PR's from Maidstone. When you have that info, get back to me as I may be able to help further. If your Foreman line is related to mine it will be early 1700's - so lots of challenging work to do before we can say we are 8th or 10th generation cousins !
Good luck, Jeremy.
