I' thought I'd better join in and explain that the photo is mine which I passed on to Daval57.
In response to Mosstrooper and Jap, yes it is the Forrest family, and thank you Mosstrooper for the link to the Slamannan census site showing details of my Great grandfather and his family from Whitburn.
I have wondered about the location, but I'm sorry to say there is nothing on the back of the original photo. There are however a few things I can tell you. The person standing on the right of the photo is my paternal Grandpa, William Meek Forrest and I guess that the others are 4 of his brothers, though I am not sure about that and don't know their names.
As to the date, for various reasons I am estimating that William is in his late 20s at the time (dob 1872)., so it's probably around the turn of the century.By 1904 he had moved to Wrexham, Denbighshire, married a local girl and had his first child. Of course the four other chaps could have travelled to Wrexham and this could be a family reunion, but I don't think so.
I say this because I do have another photo, attached, which was taken at the same location, but nearer to the tower and from a slightly different angle. Also it is of a different family group. In the original photo, it is of the chap sitting, right, with his family. He does look a bit younger to me. For this reason, I believe location is Scotland, but where, I don't know. Glasgow, perhaps? I know the family visited there around this time and my Grandpa did move back there after Wrexham.
I am making educated guesses here and am still in the early stages of finding out about my father's family, so any further observations welcome.
