Thanks for this. I actually know Norwood Green well, having lived in both Hounslow and Ealing. A lot of other London boroughs have cemeteries in Ealing, along the Uxbridge Road.
The two Wright brothers were born in Great Dunmow in Essex. They come from a family of carpenters and builders. They were both carpenters and later general builders, with William have small building firm. In the 1891 census, William is described as a builder, whilst his son is listed as a carpenter, no doubt working in the family business. Similarly, Wilson in 1891 census is listed as a carpenter.
As for the two Daniels sisters, they are from the Tottenham/Edmonton area and are related to me by blood.
Neither family have any canal connections as far as I know.
