One of Leslie Dunkling's books, perhaps the Guinness Book of Names, includes a list of names people have strong opinions about, and Muriel featured prominently, along with Bertha, Edna, Gladys and their male equivalents. So it could also just be a matter of fashion, in which case there should be a crop of little Muriels in twenty years from now!
