What is the meaning of the name Isobail ?

Isobail is Scottish Gaelic in Origin.

Isobail is a Scottish-Gaelic-tinged form of Isobel/Isabel, ultimately from Hebrew Elisheva, “my God is an oath” or “pledged to God.” The name reached Britain through Latin and Old French (Isabeau, Isabel) and medieval Iberian Ysabel, then took deep root in Scotland. The pure Gaelic equivalent is Iseabail, found in bardic poetry and clan genealogies; Isobail appears as an orthographic variant in parish and kirk records, especially in the Highlands and Northern Isles, reflecting Scots and Gaelic sound-patterns.

Documented bearers include Iseabail/Isobel across medieval Scottish nobility, while the 19th‑century philanthropist Ishbel, Marchioness of Aberdeen, popularized the Anglicized Gaelic shape. Variants and cousins include Iseabail, Ishbel, Isobel, Isabel, Isabail, Ysabel, and Isabeau; diminutives Isa, Izzy, Belle, and Bella. Meaning remains constant: devotion and oathbound fidelity.
