Whoa, you need to try to avoid some of those acres of white space at the bottom of your post.

Thought that perhaps your grandfather might have been enrolled in the Royal Hibernian Military School in Kilmainham in Dublin, http://www.richardgilbert.ca/achart/public_html/articles/hibernian/index.html but he isn't listed.

The RFC was created in May 1912 and the Army branch of the RFC was formed from the Air Battalion of the Royal Engineers which was created in April 1911 and that was formed from staff of the Royal Engineers School of Ballooning which had been formed in 1888.

The Air battalion had two Companies, No 1 Company operated airships and No 2 Company operated aircraft. https://en.wikipedia.org/wiki/Air_Battalion_Royal_Engineers

No 2 Company was based at Larkhill on Salisbury Plain which is probably your Stonehenge, because they're only about a mile apart.

Unless you have military records that say otherwise, perhaps he was still serving in the R.E. and transferred into the RFC in WW1, and if he had done that, he would have been issued with a new Regimental number in the RFC, and given his dates, he might also have served in the Second Boer War.

When the RAF was formed on 1st April 1918 all of the RFC servicemen were transferred to the RAF and they retained their RFC regimental numbers in the RAF,  and it looks like this is him in the RAF in April 1918...John Macpherson born 1877 in Cork attestation year in respect of the RAF 1916   number 220145   occupation Joiner & Sawyer.

How did we get from Brazil in WW2 to Stonehenge in WW1. ? 

Weirdly curious coincidence, there's just been an ad on the radio for a TV programme later today about Stonehenge. !

Catch you later, I've got to go and try to figure out how to pee into a plastic tube less than half an inch wide.

Death record shows William Hagan died from Cardiac Failure due to pulmonary tubercolosis due to toxameia.  It seems he drank contaminated milk while in the army and contracted TB.
So I suppose that means he did not die in service, but rather was discharged and then died at home?

Milk !, good grief. !!! Well I don't know what your source is for the fact that he drank the milk whilst serving in the Army, but if that was the case, and if he was also given the milk by the Army, and if that can be proven and documented, then his death would be classed as war service related and the CWGC would add him to their database of WW2 Army casualties, even if he had already been discharged from the Army at the time of his death. Anyway you have the Army number of the soldier on the commendation letter and if he is the man who died in 1946 that's all that you need to be able to successfully apply for a copy of his WW2 service record. I suspect that he may well have already been discharged, but his service record will sort that out, as for him possibly having been given the milk by the Army, it seems unlikely because if that had been the case other soldiers would have probably also become ill, but perhaps they did. Next main question, was there more than one death in Ulster in 1946 for that name.

Really good second pic find, you've aced that, and pics like that, are surprisingly sparse, despitethat being such a world famous structure. Anyway, that proves that I was right, it definitely was Mustapha.

Have you checked British outbound ships passenger lists for the 1940's and 1950's, haven't looked in any detail but your two names are mentioned in your two time frames bound for Brazil.

Inbound passenger lists are also available, haven't looked at those at all.

Might just be a coincidence, but might be worth checking in more detail.

"Correct board" no big deal, at least not to me, and your thread has served it's purpose, might be worth asking for a bit of passenger list checking help on the immigration or travel sub forums or whatever they're called.

What specifically is it that you're trying to find in the context of this topic. ?

H.M.S. St. Fagan wasn't lost in December she was sunk on 1st June 1940, 17 members of the crew were lost.

4 of them are listed on H.M.S. St Fagan on the Commonwealth War Graves Commission database.
