Brockley and Ladywell cemetery was, as the name suggests, once two cemeteries, and up to 1948 they were separated by a wall.
The coordinates take you to the World War I memorial in Ladywell Cemetery. There are around 100 burials in the War Plot and their names are inscribed on a screen wall, which also commemorates those whose graves are located elsewhere in the cemetery but are not marked by headstones.
Find the soldier who "bore the cross and gained the crown". He has a five digit service number ABCDE.
