Hi to everyone who has replied. To Ambly: The link you referred to is where I asked for restorations of these 2 photos. No, the photos are copies of copies of copies, therefore I do not have the originals.
To Jim1: Thanks for the 'heads up' about coming forward a generation - I'll keep that in mind.
I was hoping the photos may have been taken on their wedding day but I guess I'm lucky to have them at all, no matter when they were taken.
It's handy to know that photography wasn't invented until 1839, so thanks for that bit of info.
Cheers to all,
Michelle
