Eliza is a charming and historic given name, of Hebrew origin meaning 'God is my oath' or 'God is my promise'. It gained popularity through its usage in the works of English poet George Gordon Byron, specifically in his narrative poem 'The Corsair', where Eliza was the leading female character. In literature, it has also been used in Charlotte Brontë's 'Jane Eyre' and in Lewis Carroll's 'Alice's Adventures in Wonderland'. Eliza is often considered a shortened form or variant of Elizabeth, but it stands beautifully on its own with its unique sound and elegant simplicity.
Eliza was a moderately popular name throughout much of the late 19th to mid-20th centuries, with peaks in popularity around World War I and again in the 1980s. However, it has seen fewer births since the 1950s, with only occasional occurrences up until recent years.
