The gentleman you are searching for is without doubt my Great Uncle Reginald Evans. He died on the first day of the battle of the Somme (1/7/1916) at Gommecourt. He was serving with the 12th Battalion the London Regiment (The Rangers). His service number is 471554. He is buried at Gommecourt British Cemetery Number 2. I have visited the site on many occasions. His details appear on the CWGC website. If you cut and paste the following into the search bar it will take you directly to his page:
http://www.cwgc.org/search/casualty_details.aspx?casualty=590005Unfortunately it gives no address or next of kin. Given that he appears on the Carshalton war memorial I would guess he was still living with my Great Grand parents Hugh and Florence. My Grandad is Herbert Lionel Leonard Evans. I have asked both my dad and uncle who were unable to help any further regarding their Uncles address at the time of his enlistment. There is a medal card available but it would appear no service record. It's a shame because I am very keen on world war one history. Due to your posting I shall now travel down from Norfolk to attend the war memorial on the next remembrance sunday in order to pay my respects.
I hope the above is a help
All the best
Paul Evans
