Ian, I keep loosing my reply so will try again. Thank you for your message. I cannot find a direct link between your Hannah b circa 1840 and my records.
There are a number members of Hannah and William throughout the tree. The first is a Hannah bapt. 1753 daughter of Thomas Coope and Elizabeth ?.
There is also mention of a Hannah b 1772 twin of Mary to John Cowpe and Sarah Maux. Hannah's older brother Edward b 1764 married Jane Housely 1785. They had eight children, the eighth William died age 4. The sixth child George b 1802,a shoemaker, married Martha ? and they had three children - Edward, George and William b? 1834. Although the dates do not gel with yours there may be some link there somewhere.
