Archaic Welsh or medieval spelling of Isabel, from Hebrew Elisheba meaning 'God is my oath.'
Ysobel is an archaic Welsh or medieval spelling of Isabel, from Hebrew Elisheba meaning God is my oath. That gives the name a venerable, devotional lineage and places it within the long history of royal and saintly versions of Elizabeth.
The older spelling makes it feel especially historical and literary. In modern eyes, Ysobel feels medieval, romantic, and refined. It has the softness of Isabel with an extra layer of antiquity.
Because it is rare, it can seem especially elegant and a little mysterious. Ysobel is a name that preserves the old spelling's charm while retaining a very familiar spiritual core.
