I had done 'Untimely Deaths' as well, but it doesn't matter.
Pairs of females are really hard, though, because there are not that many females and we often don't know many of the people they're related to. Although when I wrote that one, I think we mostly did first-letter passwords, or diagonals, or all 3rd letter or whatever. We've now done so many that we often need random letter positions to make new ones ... especially if they're to have a theme.
