Meaning and history
Cydney is a modern feminine spelling variant of Sydney. Sydney began as an English surname, often traced to the Norman French place name Saint-Denis, though some families may derive from English locations with different histories. Its use as a given name later became common for both sexes. The initial C is stylistic and does not create a separate etymology. A notable bearer is American professional bodybuilder Cydney Gillon, a multiple winner of the Ms. Olympia Figure competition.
