Jane is a feminine given name. It is the English form of the Old French name Jehanne, which was an old feminine form of the male name Johannes or Ioannes, a Latin form of the Greek name Ἰωάννης, which is derived from the Hebrew name יוֹחָנָן, a short form of the name יְהוֹחָנָן, meaning "Yahweh is merciful". The name was first used in large numbers in the mid-16th century for the daughters of aristocrats as an alternative to the more commonplace Joan. The two names have alternated popularity. In the early 19th century, Jane was again seen as a name with a certain amount of glamour. Joan became more popular in the early to mid-20th century, when it was ranked in the top 500 most popular names given to girls in the United States, but the name has again been displaced by Jane on the popularity charts in the 21st century.
