Hi Thunder Monkey,
No connection at the moment, I'm not aware of any of my lot being in the Gt Bromley area, but when you get back a generation beyond John 1809 who knows? I haven't researched the siblings of my Warner ancestors, so who they married and where they went I have no idea, been too busy chasing ancestors.
John Warner and Elizabeth Sewell married at Sandon in 1802, they had nine children 1803 to 1822 but not one was named John as you might expect, nor one named Elizabeth for that matter. There are a couple of gaps 1803 to 1808 and 1814 to 1818 when another child or two could have been born but to date I haven't found any.
Regards.
