I've found the christening records for the children of the marriage at St James, Paddington, spread over about 10 years, from Family Search, so the church was an important location for them.
However, I cannot find the marriage of George Bilney and Charlotte Coney in or around 1828. I'm pretty certain it would have also been at St James, Paddington but I can't be 100%.
I don't know where the records would be.
Could anyone help ?
