I've just borrowed a book about girls taking the place of men as boaters on the Grand Union Canal [London to Birmingham] during the war -1940s while men were in the Army etc. Does anyone know of boaters or other canal workers having found them listed on any census? I have seen gate keepers & Lock keepers but no others. If they were still travelling until very late afternoon, it would be hard for enumerators to drop of their forms for people to fill out. Is this another way people have lost ancestors until they eventually gave up as boaters or simply left their families in the towns.? I have a fondness for the canal boats which are available to hire these days but will never get to do so. Couldn't resist the book.
