The Story of Sidney
Sidney originated as an English surname derived from the French town Saint-Denis (near Paris) or possibly from the Old English sid ig meaning wide island. It became a given name honoring Sir Philip Sidney, the celebrated Elizabethan poet and soldier. Though traditionally male, Sidney (often spelled Sydney) shifted to predominantly female use in the 20th century, particularly in the United States.
Sidney for girls gained momentum in the 1990s through characters in TV shows including Sidney on Melrose Place. The city of Sydney, Australia's iconic harbor city, further cemented the spelling Sydney as a popular girl's name in English-speaking countries.
Sir Philip Sidney was one of the greatest Elizabethan poets, and his name was given to children for generations as an honor. Today, Sidney and Sydney are among the most successful gender-switch names, having transitioned from exclusively male to primarily female use.
