If you have read them, could you please reveal some of the title characters' names in the comments?

I never made a decision not to read the above books. I was discussing books with a friend and noticed that I always confused the first two in my head. Then I had to assuage my curiosity and see how many other "wife" and "daughter" titles I recognized but never read.

I have however, read:
The Firework-Maker's Daughter (Philip Pullman picture book)
The Meaning of Wife (Anne Kingston essays on the "Wedding Industrial Complex")
The Man Who Mistook his Wife for a Hat (Oliver Sacks, non-fiction)

If you do a search on Amazon, though, you find a lot of "The [adjective] Son", as opposed to "The [noun's] son. Do you think the current titling of [so and so]'s daughters is just a trend, a way to market a story as taking place in the past? Or is there an element of (misguided) nostalgia in the titles? Or am I reading too much into it?
