I have been researching on the GRO and kept coming across the district Castle W. What does the W stand for and where is it in Carlisle? The other question I would like to ask is, is there another site that you can access for WW1 information apart from the CWWG site. I have found an entry for one of my relatives but it doen't give an age and I would like to confirm a year of birth to tie up loose ends. Any suggestions welcome.
