What does Isobel mean?
Isobel means “God is my oath”.
Isobel is a Scottish form of Isabel, a name that ultimately belongs to the Elizabeth family. Its older Hebrew elements are traditionally understood as God is my oath. The shift from Elizabeth to Isabel took place through a long history of European usage, so Isobel has a deeper background than a modern change of one vowel.
The o spelling gives the name a recognizable Scottish identity while keeping it close in sound to Isabel and Isabelle. Modern fiction has also made it familiar through Isobel Crawley in Downton Abbey. That character is one association among many, rather than the origin of the name. Parents who want a connection to an Elizabeth or Isabel can use Isobel as a related established form with its own regional history.
