The name Margery ranked 823rd in popularity for females of all ages in a sample of the 1990 US Census.
Though this name has fluctuated in use, it has been quietly present throughout the last century.
English speakers of the Middle Ages would have found Margery a more familiar name even than its source, Margaret.
Some speculate the newer (and now more popular) spelling Marjorie arose from its sound-alike similarity to marjoram, the name of an aromatic herb. The obscure origins of that term are entirely separate from those of Margaret.
