Thank you all,
mudge that's the reason we thought a wedding party. it is a picture that was in someoones possesion, they put it in the surrey mirror hopiong someone would recognise somebody and my grandma spotted her uncle (standing far left). we do no know which relatives of the original person's it is. all we have established is that gran's uncle lived in the same road in caterham as many of the original persons ancestors. i suspect it may be someone in the road that was marrying bu without a date we can't even begin to find out whose.
thanks all for the restors and dates, it's very helpful.
