Can anyone help me to find out about my Grandfather's war service? I've hit a big brick wall!

He was in WW1, but all I've been able to discover is from the 1918 Absent Voters List. It gives his address 86 Dacre Street, Birkenhead, and his regimental number; 112564 GNR 31st A.A. Co. R.G.A.

His other details are below;

NAME: James William Wilson (1895 - 1957)
BORN: 03/10/1895 in 42 Watson Street, Birkenhead (birth record 8a, 475.
PARENTS: William Wilson (1867-1949) and Mary Hall (c1866.)

If anyone here has experience with researching army records, I would greatly value your help or advice.

Hi,

can't find anything on Ancestry for him, you probably know that a lot of records were destroyed, It looks like he was a gunner in the Royal Garrison Artillery, they fired the big heavy stuff. I can only suggest you contact link

Good Luck

Gold Moon, Bebington Library, if you are near enough, have a Family History Research group once a month. Can't remember which day but they are very good and can help you access anything.
Give the library a call.

Ask to speak to the manager Graham Knowles.

I cannot see a Wilson with a regimental No. 112564 in the Medal card Index.

As Bert1 says a lot of records were burnt. I don't see him in the Service records or Pension records, but he should be among the Medal Card Index. Do you have any of his medals to check the number?

Thank you so much to everyone who has replied!

@Bert1: That link has some useful email contact addresses, I'll be writing to some of those!

@Granny: Thank-you, I didn't know about this! I'll be looking into it...

@OxtonHill: Sadly, my Mum doesn't have ANY of her Dad's medals. Her Mum's second husband quietly got rid of them, probably sold them. This is why I'm finding it very difficult to find out anything about him, there's very little to go on.
