MURIEL.  Old English name, meaning "perfumed," from Greek muron. 

    The pretty old English name of Muriel, meaning perfumed, was originally derived from the Greek muron, any sweet juice distilling from plants and used for unguents or perfumes, muron itself being derived by the ancients from muro = to flow or trickle, or, according to Athenaeus, from murra = the oil of myrrh, though the word is probably of Oriental origin—perhaps connected with the Hebrew môr.  The word is not of uncommon occurrence in Greek literature, and even enters into a proverbial saying, "Sweet oil on lentils", meaning "Pains thrown away". 
     Met with in old English registers and amongst our old song writers, it had practically sunk into disuse until quite recent years; but is now surely and deservedly gaining popularity.  A fresh impetus was first given to Muriel probably by Miss Dinah Mulock's (Mrs. Craik's) popular book, John Halifax, Gentleman—where the little blind heroine has the name of Muriel, "Muriel—little unconscious, cooing dove"!... "Yes, those pretty baby eyes were dark—quite dark.  There was nothing painful or unnatural in their look, save, perhaps, the blankness of gaze which I have before noticed... She never had seen—never would see—in this world"... (Girls' Christian Names, Swan, 1905)
