WW1 Photo Postcard - Douglas and Ethel

K Burhouse sent us this photo. She wonders if anyone recognises the couple... maybe living relatives. She wrote:

"I have a photo from WW1 period of a man and a woman (possibly married couple) which was taken by the Newport photographer Louise M Smith. I'm trying to identify who the two people are. The man is wearing a Royal Army Medical Corps uniform with Corporal stripes. The writing on the back says 'To wish you all everything that is good this Xmas. With love from Douglas and Ethel'."
