I dislike the names on the whole myself, but I got to point out that they're called by their mns.
Kyd was named after
Thomas Kyd, a 16th-century playwright (see here:

David admired
Thomas's writings, apparently. Miller was
David's mother's maiden name.
I don't know where West and
Madelaine came from. I wish they'd spelled it
Madeleine though.
Miranda (who wonders why the Duchovny kids didn't get episodes named after
them)
