Meaning & origin
Isobelle is a rare French-influenced spelling of the classic name Isabel, sharing the enduring meaning 'God is my oath' rooted in Hebrew origins. First recorded in U.S. data in 1914, it peaked in that same year, likely reflecting a brief flourish of this particular variant before falling into obscurity. By 2025, only about 1 in 229,610 baby girls received the name, placing it at rank 11,932. Its trajectory has been stable over the past decade, with no strong revival in sight. The name's top states are not listed, indicating that use is scattered rather than concentrated. Isobelle offers a distinctive alternative to the more common Isabelle or Isabella, appealing to parents who favor a vintage, underused form.
Isobelle is a French variant of Isabel, which itself derives from the Hebrew name Elisheva, meaning 'God is my oath.' The form Isabel emerged in medieval France and was carried to England after the Norman Conquest. Isobelle, with its 'e' ending, is a less common spelling used primarily in the 19th and early 20th centuries, often influenced by Scottish usage, where Isabella was the standard form.
