Tim,
Thank you for the details. Sorry I've been off line; we were due to move house at the start of June and were hard at it, packing etc; too busy to respond. We were then gazumped by a cash buyer but rather than lose our sale we decided to carry on and live with relatives, go on holidays for a "few" weeks, until a new, 2nd purchase can go ahead. Trying times, and all our stuff is now in storage and we are living from suitcases at various relatives or doing short weekend breaks. Hey ho, worse happens at sea.
From your response, it seems I need to start afresh. My granddad certaily didn't die in the 1920's, in fact he passed in 1990, just before I went off to Gulf War 1. So from the details you have access to, that my cousin & I had not found, we must have the wrong guy.
The reference to 202998 J R Wilson was tracked down by a cousin 3-4 years ago, who is into family research. I think that he had gone through all (Manchester???) records for a John Robert Wilson (and quite a lot of just Johns or just Roberts) and for some reason he ended up with that number / record. Whilst there seem to be very many "just" John or Robert individuals I gathered that there were not many "John Roberts" and certainly the date of birth in 1998 (3rd July) helped narrow them down.
It was from a single conversation that he had with me that anyone knew about his WW1 service, he never spoke of it to his three sons (other than when I asked them separately, they all knew the one word "Salonika").
I separately knew (from that brief conversation with my grandfather, the only time it seems he spoke of his experiences) that he served in Salonika and then went back to France towards the end of WW1. He talked to me about how lucky he was to go first to Salonika (and possibly Egypt, Suez? I'm a bit hazy on that) before coming back to France for the final months of the war. He spoke about being or working with messages, morse code, maybe signalling and runnign phone wires. He was reminiscing about some good (and safe) times away from the carnage in France, when he started talking about (seeing? being involved in?) pretty grim trench warefare and advancing to contact under fire (as I knew the term from my Army service). He then choked up and said no more.
He'd also mentioned being in or passing through Bicester (I was just being posted to MOD Bicester, which is why he started talking to me about things he'd never spoken of at all).
That puzzled me, since there were only local militia units around Bicester in WW1 until the RAF arrived, but then I realised that the railways from north to south passed through of past Bicester back in 1914-1920s. There were a lot of training camps down around Bordon, Aldershot, Deepcut and Blackdown. Access from the north was by train and Bicester was one of the routes. There was also a Red Cross Hopsital in Bicester for WW1. But I never heard that granddad was injured.
I don't know if the Army Medical Service WW1 records survived or are accessible, but I know they have a museum near Aldershot, Ash Vale. (The Army Medical records from 1991 from Gulf War1 didn't survive, they were destroyed in theatre, which affected my pension!!!!).
When I started reading up on WW1 myself during lockdown time, I didn't initially appreciate the sheer number of Lancashire and related regiments and corps, and service units that would have recruited from Manchester. The family lived in (west) Gorton back then, with a few links to the railway companies based there. I assumed that the only Pals to look into would be Manchester Regiment Pals. And I think I read somwewhere that 13th Manchesters recruited around Gorton and Ardwick.
And from that I eventually whittled down to the 13th / 9th Battalions being the only unit mix that fitted into a Salonika and late-1918 France deployments. And that corresponded with my cousin's tracking down Private 202998 .....
Family knowledge was that he'd been "a Pal" but as he never spoke to any of his sons about it the assumpation was that he'd been a Manchester Pal.
I will have to restart my research, once I get the opportunity.
My wife and I are still "temproarily" living with relatives between Hampshire and Yorkshire (possibly County Durham in a fortnight if the soliciotrs do not pull their fingers out). So I am not really in a place to carry out research. My laptop doesn't come everywhere with us.
But one day I will have time and access to internet etc, and maybe try researching elsewhere.
Thanks again for providing such good, information, we can cross that one soldier off our list.
