Cartes de Visite Album, Page 46

[RobinClay]

My grandmother's grandmother was Martha hammond Thornewill (of Burton-o[-Trent) nee Wright (of Eyam).  I have her album of some 150 Cartes de Visite, with not very many of them identified.    I have scanned the empty pages, and front & back of each card. 

Can you tell me what date each of these is from, please?  That will help me to establish the year of birth, which just might enable me to identify the subject !  Information about the Studio would be of interest, too.

Page 46 contains three men and a woman.

I'm posting the lo-res versions, so please don't bother to try to improve them.

I am gathering the comments to store in a file alongside the pictures, and, when finished, it will be quite a task to analyse them all and draw deductions as to the identity of some currently unknown.

For Page 45, see

which also contain links to the previous pages.

Here's 46A.  It is inscribed on the back, simply "Derby".  Your guess is probably better than mine as to the significance of that !  But a guess as to the age of the man, and the date of the photograph would suggest an approximate date of birth, which might help to identify him.

Here is the lady, 46B.  Is this, perhaps, Queen alexandra again ?

[RobinClay]

And here's another mysery character, 46C; the back is inscribed "Fairbairn", but that conveys nothing to me.

... and finally, 46D.  If you don't recognise the picture, the inscription on the back leaves no doubt - "H.R.H. The Prince Consort".

Why, oh, WHY did she not inscribe every one as she inserted it?

[Seoras]

Could the one with Derby on the back be the Earl of Derby Prime Minister. I'm not sure but is 46C another PM, William Gladstone.

Don't think it's Gladstone, I think it's this guy:
