Stilly -

If he is - or was - a pro photographer, odds he'd find the album should have been very good, assuming he got sentimental enough and had the time to "reflect on his career" by going through the older stuff.

Odds that they'd still be married probably a little less.

Odds that he'd bother to look for them, close to zero - except for the mention that he "was reminded by a chance meeting" with one of their relatives. (?)

But with all the odds stacked against them, it's still a very happy little story.
