Have you tried to contact the owner of the photo to ask if they could take a closer look at the original photo?

Sorry about the icons I haven't put them in they have appeared as I've used more than one ?

Good Luck!

Thanks.  Greenwood is such a common name in that area, and the name Sarah doesn't connect with my family, so I think chances are it isn't my great great grandfather.  It might be the same man whose advertisements selling farm machinery are frequent in the local newspapers of the time, and even then probably not.
