I've inherited a Victorian portrait photo album of my ancestors (and friends?!). Unfortunately, I have no way of knowing who in the family was its original owner -- which might help with identifying some of the folk in it. (No helpful names written on the backs of photos, of course!) Identifications are proving very difficult!

The photos include about a dozen of different individuals taken at different portrait photographers' studios in Cardiff. Yet I do not know of any connection between my London/Hereford-based family and ANYONE in Cardiff, so this is a real puzzle!

On the back of one photo in the album of one of my "main players", Hereford-based Tom, is written Tom's address, gently crossed through, and then "please return this, being one of a pair" (also gently crossed through) and then: Mr Minley (just possibly "Munley"), 47 Grange Gardens, Grange, Cardiff -- a Cardiff address; hurrah! And the matching pair photo of his wife, Eliza (also taken in Hereford) has written on the back: M Skye, 34 Corporation Road, Lower Grange, Cardiff -- another Cardiff address! I would of course like to try to find out more about these two individuals as they provide a possible Cardiff connection; but having no forenames and no knowledge of their family relationships, and being a relative newbie to genealogy, I have no clue where to start! Can anyone advise me, please? Tom & Eliza were married in 1879 and died around 1910. Unfortunately, I live in Texas and so can only research on line.
Many thanks for reading this far!
