Hi
Not sure if this helps.
I have only managed to look at a couple of trees that say Thomas Green Williams b1833 is the son of Thomas Williams and Sarah Palmer, Sarah Palmer born 1784, surely this cant be right she would have been aged 50ish, when it seemed she had this one and only child.

There is a marriage for Thomas Williams to Christiana Green at St Johns Bristol 18/5/1829 that would make more sense, it was common to give a child its mothers maiden name as a second Christian name, maybe St John Bristol woukd be a good place to start looking

She
