I am not familiar with the areas of London that you have been talking about, but my Gt grandfather Galley was born in what is referred to as Blackwall(on his marriage cert) and his brother is listed as being born in Poplar, and therefore it is said that they are Cockneys. Born within the sound of the Bow Bells church. Are the churches that you have been talking about in this area? I am still tracing my Galley name in Kent and can't really enter the discussions until I can go back in time a bit further,but it would be interesting to know about the area. Regards Jim
