Faith and Hope, and…?

This year in the office we are thinking a bit about what the meaning of Hope is. So here's a bit of a puzzle for you all (with no offense to the dear babies and family)

Last week, conjoined twins were born in London. They were named Faith and Hope. Today, the BBC reports that after the operation to separate them, Hope died.

Now what I'm wondering is what persuaded the twins' parents to call them Faith and Hope? And what determined which twin got which name? Did they have faith in Faith and only hope for Hope?

Did their decision about the names in some way determine the fate of the babies, or vice versa?

It intrigues me that Faith continues to survive while there turned out to be no hope for Hope.

I also wonder what happened to the third baby, Love, who never even existed. Is it because the greatest triplet is missing that the others are failing to thrive?
