MARJOLAINE.  From the French word for "marjoram." (A New Pocket Dictionary of the French and English Languages, Nugent, 1826).

... If there could be a time when Jean-Louis would rather not meet Marjolaine, this was the time.  And it was precisely Marjolaine whom he met, a little way out of the village.  That is, he ran against her, for she came rather suddenly and quickly round the corner of a road at right angles to the one along which he was rushing, and he very nearly knocked her down.  And how can one very nearly knock down the beloved of one's heart, and continue one's wild career without apology?... (Littell's Living Age, v.168, 1886)
