Jane
fem. proper name, from French Jeanne, Old French Jehane, from Medieval Latin Johanna (see John). As a generic name for "girl, girlfriend" it is attested from 1906 in U.S. slang. Never a top-10 list name for girls born in the U.S., it ranked in the top 50 from 1931 to 1956. It may owe its "everywoman" reputation rather to its association with the popular boy's name John.
Jenny
fem. personal name, originally another form of Jane, Janey and a diminutive of Jane or Janet; in modern use (mid-20c.) typically a shortening of Jennifer. Jenny is attested from c. 1600 as female equivalent of jack (n.), and like it applied to animals (especially of birds, of a heron, a jay, but especially Jenny wren, 1640s, in bird-fables the consort of Robin Redbreast). Also like jack used of machinery; Akrwright's spinning jenny (1783) is said to have been named for his wife, but is perhaps rather a corruption of gin (n.2) "engine."
