You have a valuable photograph there.
[You may wish to consider sharing it with PRONI, to help preserve it publicly for posterity.
There are many photographs around, but very few with such valuable annotation on them.]
In the meantime, to help out the Internet-crawling robots with indexing the location and the names, these texts should supply sufficiently differentiated fodder for them:

Here is the image of a postcard of the whole school facade (date unknown):
[The building on the left seems to present a wide doorway flanked by two bay windows, just like your (restricted view) photograph.]
http://www.postcardsireland.com/postcard/mourne-grange-kilkeelIts founder is buried locally, with family (?):
Allen Sausmarez CAREY
Florence Caroline CAREY (wife?)
Patrick Sausmarez CAREY (son?)

https://en.wikipedia.org/wiki/KilkeelPerhaps, son(?) Patrick CAREY's penchant for drama was picked up from one of the main themes of his father's school?
"But the 50’s were a golden decade, under the direction of
Patrick Carey, headmaster at Grange primary school in Kilkeel. His skill and dedication sent Newpoint Players’ reputation rocketing. The B.B.C. selected the Newry society to participate in the programme, “We do it for love,” and they were also chosen to represent Northern Ireland at the Festival of Britain. Then came the ultimate accolade at the All-Ireland Drama Festival in Athlone, winning a special award for “The Duchess of Malfi,” following by the premier prize for “Arms and the Man” in 1958. This was broadcast on Radio Eireann."

Given Kilkeel's great sea trading history, I tried hard to find a naval connection for ROSSEL.
One (remote) possibility is a 2nd Lieutenant in Rear Admiral Bruni D'Entrecasteaux's French expedition to the Polynesian islands in the early 1790s, who eventually had to take over control. Monsieur M. ROSSEL seems to have had an island named after him.
http://nzetc.victoria.ac.nz/tm/scholarly/tei-BucExpl-t1-body-d16-d7.htmlThis is roughly around the time of NELSON coming to prominence.
So, perhaps, the houses were named ROSSEL, COCHRAN, SAUSMAREZ, (NELSON), ...
[But this is pure speculation, and there is probably a more prosaic solution.]
Just the sort of spirit that a male independent school of the time would be trying to inculcate within its pupils.
[Boldness, confidence, courage, determination, prowess, comradeship, leadership, decisiveness, persuaviness, oratory, competing, battling, winning, out_smarting, strategy, knowledge, etc.]

Reckon that the identification of a Guernsey connection of the founder is secure though.
The CAREY's are long established there - since the 14thC!
They also seem to have married in to the ALLENs.

Thus reckon that Fadge's assessment of the "overseas" nature of the floppy hats can be met, almost.
They are just the sort of thing that a gentleman on a sunny windswept island in the Empire might wear.
Jamaica, Bermuda, ... , Malta, ... , Ceylon, ...., Guernsey!
[The Channel Islands are as far away as you can get from the North of Ireland within the British Isles, without having to use a passport. Great place for producing early-season vegetables. Lovely young tomatoes and new potatoes (though no use for producing potato bread!).]

I am much interested in connections between Guernsey and County Antrim, so very glad that such turned up unexpectedly in this research.
My own family were there in the mid-19thC, but why is a mystery.
[Solving such might clear our 18thC boundary log jam!]
Possibly with earlier connections to the Napoleonic Wars.
[General Henry SEYMOUR-CONWAY (brother of Lord Hertford - owner of most of SW Antrim - Lisburn et al.), who was M.P for County Antrim then Chief Secretary of Ireland, was also Governor of Jersey for many years, organising the defences of St. Helier, such proving effective when the French attempted an invasion a few years later. etc. etc.

Hope that you didn't mind the colloquialisms.
Some can find them a tad "affected".
[I had to send my son to a small English independent school.
He returned every weekend with these phrases, much to my amusement.]
Anyway, think that that is all that I can help you with from online searches.
Further answers lie in PRONI (and maybe the Priaulx Library, St. Peter Port, Guernsey).
All the best with your further trawling of the murky depths!
