Hi Sarah,
Could he be the David Woodward, son of Jane and the late Adam, husband of Agnes Williams? There is a soldier of the same name in the Royal Welsh Fusiliers on the Commonweallth War Graves Commission website:www.cwgc.org
The parents and wife give addresses in Flintshire, his age is shown as 26 and date of death 27th March 1917.
His name appears on the Jerusalem Memorial in Israel.
