:):) You will let me know what. ? Their service records don't appear to have survived, and medal records don't usually contain any biographical information.
However, in this case there is another likely clue in the medal record cards, which are attached.
WR337370 Pioneer Ernest May Royal Engineers Waterways and Docks does have a card, but it isn't for campaign medals, and he didn't have any campaign medals, because he didn't serve outside the U.K., probably because of the the length of his service, and the circumstances of his discharge.
His record card is for the issue of a Silver War Badge (SWB), and SWB records show dates of enlistment and discharge, and they also show the age at at the time of discharge.
He was discharged because of sickness on 16th October 1918 and he had enlisted on 10th June 1918, and his age in October 1918 was 43 so he was born circa 1875.
His full name was Ernest George May he was aged 43 and was born in Kent.
He had suffered from chronic bronchitis since childhood and he walked with a limp due to a pre war ankle injury caused by a fall from a ladder, jeez, what state did a recruit have to be in before he failed an enlistment medical. ?!!!
So you can rule him out, assuming of course that the birth year that you have for your relative is correct, and in any case, I can't imagine that a man who enlisted into the Royal Engineers in 1918 would have been issued with the prewar design badge, all of the stocks of which would probably have already been issued well before that.
Which means that your relative is either...
67183 Sapper Ernest May Royal Engineers...killed in 1915 in Galipolli
75842 Sapper Ernest May Royal Engineers who survived the war and was discharged to the Class Z reserve at the end of the war.
http://en.wikipedia.org/wiki/Class_Z_ReserveIt's circumstantial of course, but it seems unlikely that if your relative had been killed in WW1 that no memory or mention of that would have survived within the family.
There is a definite way in which you might be able to resolve the matter, via the marriage certificate of 67183.
That will give you his age and his father's name and occupation.
He married EMILY LOUISA HUMPHREY in the Camberwell Registration District in London in the April/May/June quarter of 1908 Volume 1D Page 1537.
