Meaning and history
From a medieval French nickname meaning “white” or “fair-colored,” Blanche ultimately derives from the Germanic word blankaz. An early bearer was Blanca of Navarre, the 12th-century wife of Sancho III of Castile, and her granddaughter Blanche, who married Louis VIII of France, helped make the name more common in France.
Blanche moved from #907 to #912 for girls between 1963 and 1964. Its highest annual birth count came in 1917, with 2,836 births.
