The folk in Malton seem to be particularly helpful:  I am also grateful to John who manages the Malton History website  (which has some terrific old photos) and who located the following advert from the Stamford Mercury of Friday 7 Aug 1891:

"GROCER - Wanted at once, a young Man as Grocer, to sell goods in the country and make himself generally useful, look after his horse, and live in.  Send reference.  None but pushing young men need apply. - J.Appleby, Malton"

Perhaps the successful applicant is shown in the main photo at the top of this page?

There is also the Malton and Norton Community website which includes lots of historical information,  including lists of past and present occupants of the main streets in the town.

The Appleby family from Malton seem to have made regular appearances in the local Press:

The Driffield Times of 17 jan 1875, reported that John Appleby, provision merchant of Malton, was one of a number of Malton residents who were vehemently opposed to compulsory vaccination – several of whom pleaded guilty to refusing to have their children vaccinated, stating they would prefer to be imprisoned.  Appleby and three other Malton residents were fined 5s plus 5s costs.

In 1877, Mr J Appleby was appointed President of the Malton branch of the Anti-Vaccination League which was inaugurated at a public meeting held in the Spittle-street School. The report in the York Herald of 29 March 1877 stated that “the efforts of the association, would be directed against the compulsory vacinnation law, the repeal of which is to be attempted to be effected by means of lectures, essays, public meetings, and the distribution of suitable literature.”

There were further incidents concerning John Appleby’s grocer’s shop (mainly thefts) but a more serious report concerned a motoring incident ... The Yorkshire Evening Post of Saturday 27 jun 1914 reported on “What came of a lighting a cigarette while a friend held the wheel” – when a motor mechanic was summoned for driving a motor-car to the danger of the public.  Apparently whilst Mr John Appleby, his wife, nursemaid and child in a perambulator were walking on the footpath in York Road, when a car mounted the footpath, wrecking the perambulator and knocking Mrs Appleby, the nursemaid and the child over, causing bruising.  It seems the defendant (a motor mechanic) was not driving the motor car himself but was asked to hold the wheel whilst the driver lit a cigarette.  The mechanic turned the wheel the wrong way!  He was fined £5, costs and solicitor’s fees.  (With thanks to John from the Malton History website for sending these extracts)
