Its a family photo. The man in the center is my grandfather, Bill Robinson, an Alberta rancher. He was born in England (his land owning farmer father taught at Cambridge)...I know its a General because that is General Kelly who was his brother-in-law, married to my grandmother's sister (to his right, who in her turn had previously been married to the brother of Captain Oates of Scott's South Pole expedition fame). My grandfather returned to England with his wife and children when war was declared in 1914 and luckily survived to return to the ranch in Alberta when it was over. Thanks for the identification. I guessed as much (3-stripes) but will have to dig out some better, later photos that show him in full uniform. As far as I know, my grandfather never received much formal military training. His top drawer accent and his riding ability were apparently sufficent.
