Murielle is of French origin, derived from the French word 'muriel', which means 'sea fortress'. It is a unique and elegant name that has gained popularity over time, though it remains relatively uncommon outside of France.
"Murielle's popularity as a baby name peaks in the mid-20th century with spikes in the 1920s and again in the late 1980s to early 1990s, after which it experiences a decline."
