Jane for Friday
he don't like his boring job, no
Jane for Saturday
all the girls look the same
and Janes for Sunday, too
anyone who ever had a heart
all of the flower ladies
Jane seems the perfect name to fit any kind of story, less a blank-Doe slate than an inspiring, mysterious classic. Jane gets more love as a middle name than a first, and I think it's less common than people assume, at least in the US — it's currently at #384 on the charts, and last peaked at #35, in 1946.
It's a feminine form of John, of course, and has lots of lovely variants — my favorites include sweet, retro Janet, Dutch diminutive Jantine, underrated Janine, Icelandic Jóna, punk rock Sheena and Welsh Siân ("SHAH:N").
