A little bit of info re Mervyn and his car and where he was in 1913.
If he did drive to Dorset in 1913, he did so with an expired license ! Found this wonderful piece in the Middlesex Chronicle for Saturday Jan 31 1914....
"Mervyn O'Gorman, of 21, Embankment Gardens, Chelsea, was summoned for driving a motor car at Staines-road, Sunbury, on December 29th, at a speed exceeding 20miles per hour, and also without a licence. P.S Jones deposed that the speed of the car was 34miles 1083 yards per hour. Defendant's licence had expired in February, 1913, and it was renewed the day after he was stopped, a space of ten months intervening. A number of previous convictions were proved. Mr Parkes, who appeared for the defendant, said O'Gorman had no occasion to look at his licence and was not aware it had expired. Fined £5 for excessive speed and £1 for driving without a license."
So he most certainly had a car in 1913, and liked to drive at nearly 35miles an hour !
But it does raise an interesting possibility. London to Dorset with a speed limit of 20miles an hour (poss higher on some roads, but surely nothing above 40 ?) is a very long journey, and not one probably made in a day. You would probably split your journey half way for a night or two. Could the garden images be at where they possibly stayed for a few days mid journey to Dorset ? They could have taken the trian of course, but still intriging.
Another newspaper article from Friday August 29th 1913, says
"Army Flying Corps
Fine Demonstration Given at Farnborough
Theer was a fine demonstration of the progress made in aviation by the Royal Flying Corps yesterday evening, when General Henderson, the newly appointed Inspector-General of Military Aviation visited Farnborough. The general was conducted through the sheds by Mr Mervyn O'Gorman.
General Henderson afterwards made an ascent in the Beta Airship. He also saw Mr Ronald Kent take up his equerry, Major Broncker, in the B.E No 4990, the fastest biplane the Army at present possesses. Ascending to a height of over 2,000ft the biplane made a tour of Farnborough Common, and then descended safely. General Henderson's pilot in the Beta was Captain Waterlow, of the Royal Flying Corps.
The Inspector-General subsequently saw half a dozen biplanes ascend together to a height of 2,000ft, and witnessed some clever feats of volplaning and banking. The weather was beautifully fine, and the conditions were perfect for flying"
So he was in Farnborough, Hampshire on Thursday August 28th 1913, West London on Sunday December 29th 1913, and yet another newspaper report has him in Aldershot for an inquest on October 15th 1913.
