A general servant carries out a whole range of jobs as opposed to a specialist, e.g. a footman, gardener etc. A domestic servant is a female servant who works in the house. You sometimes see the term general domestic servant where she does any type of work as opposed to a domestic servant who is specifically a cook, laundrymaid, housemaid etc. Not sure about 'daler'. Possibly a mis-spelling of 'dealer'?
