I have had a look through the Shirley family, and I think I have identified a few of the family as soldiers serving through WW1. I don't have time today to put everything together, but the I thought I would update you on the ones I posted above. Some are family to John William Shirley, others are not.
As posted above:
1. Albert Shirley, of 122 Loyd Road, Northampton, a Private in the 1st Battalion of the Northamptonshire Regiment. Noted as "Wounded & died in hospital in France"
He is listed on the Commonwealth War Graves Commission as: Private, No. 9355, of the 1st Battalion of the Northamptonshire Regiment - died on 10th December 1914 and buried at Grave No. I. B. 20. in BOIS GUILLAUME COMMUNAL CEMETERY near Rouen. He is shown as the son of Mr. and Mrs. Shirley, of Queen Street, Upper Weedon, Northants; husband of R. F., Shirley, of 11, Queen's Road, Northampton.
This is the cousin of John William Shirley, son of William Shirley's younger brother George.
2. Alfred George Shirley, of 65 Ivy Road, "72 Army Ordnance Corps Tipner" (no idea what the 72 & Tipner refer too!)
Serving at the Royal Navy Ordnance Stores at Tipnor, Portsmouth (Room 72?)
I think this is probably an unrelated Alfred George Shirley RN, born 4-5-1891 at Saltash, Cornwall – he is serving overseas in the Royal Navy in 1911 Census.
3. Arthur Shirley, of 24 Ambush Street, a Corporal in the 5th Battalion of the Northamptonshire Regiment
This is Arthur SHIPLEY, Corporal, No. 20698 Northamptonshire Regiment and Labour Corps No. 161940, and is unrelated.
4. James Henry Shirley of 7 Weston Place, a Private in the 3rd/4th Battalion of the Northamptonshire Regiment (a training battalion in the UK)
James Henry Shirley was transferred to the Leicestershire Regiment thereafter (No. 33279) and later rejoined the 4th Northamptons after the war (No. 5877062).
I think this is probably James Henry Shirley, b. 1878 – son of George Shirley, and brother of Albert Shirley, above.
5. John Shirley, of 14 Overstone Road, a Sergeant in the Northamptonshire Regiment Territorials (4th battalion)
The 1918 Absent Voters list describes him as No. 225060 a Sergeant in the 4th Reserve (Training) Battalion of the Northamptonshire Regiment - he is still at 14 Overstone Road.
I think this is probably John Shirley, born at Bethnal Green, circa 1888 - a whole family by the name of Shirley moved up from Bethnal Green to Northampton in the 1900s. This man appears to be from that family.
6. Thomas William Shirley, of 110 Loyd Road (Attested under the Derby Scheme but not yet called up - Group 38)
I'm still not sure on this man. Group 38 was for married men born in 1886 who were due for call up on 29-5-1916. Group 38 is consistent with William Shirley, the third son of George Shirley. However, that doesn't explain where the "Thomas" part has come from!
I will post more later, probably tomorrow.
