Hi Ainsley,
His full name is William Henry Edward Wilkinson, born 18.1.1887 in Kennington, London. He married Lilian Maud Tabor on 5.8.1913 in Hackney, London.
I've scanned his right shoulder but there's not a lot of definition...the last character looks like a 7.
Hello Hackstaple,
Thanks for your input. There's an Edward Wilkinson from Kennington b.about 1888 in the Tank Corps in the WW1 Service Records, and a William Henry Wilkinson, a 2nd Lieut. gunner in the RFA in the WW1 Medal Rolls Index Cards (Regimental number: 1620, 680443) - but no idea if either are him.
Regards, Fred
