Hi Marcie,
Came across this 'Deaths on Service' obituary in the Glasgow Herald dated 11th April 1918
O'May
Died of wounds received in action on 3rd April, Captain W.S. O'May, H.L.I., aged 27, beloved husband of Margaret C.D. Marshall, Dunmar, Hodge Street, Falkirk, and second son of the late Daniel O'May, Glass Merchant, and Mrs O'May, Stanley Cottage, Falkirk.
