In 1818, English zoologist William Elford Leach named nine new genera of parasitic isopods: Anilocra, Canolira, Cirolana, Conilera, Lironeca, Nelocira, Nerocila, Olencira, and Rocinela.

Each of these is an anagram of the name Caroline (or its Latinized form Carolina). But Leach was not married and had no known relationship with any woman of that name.

The genera stand as a “tantalizing puzzle for posterity.” More here.
