Reply to Ruskie re my grandfather. He may have got the job because the family were stonemasons and perhaps gt grandfather had contacts with the church or the undertakers. Most of my paternal ancestors were hatched, matched or despatched in one or other of the St Pancras Churches.
Incidentally the Old Boot pub, which NB mentions in his trip to Edgware, survived until 1965. If you are looking at google maps it was on the North East corner of the Junction of the High Street and Station Road.
