The first element of the source name makes literal reference to the yew tree, whose wood is used to make archery bows. This name travelled with the Norsemen to all parts of Northern Europe in ancient times. However, it converged with certain local names to create forms in various languages.
For instance, use of this name among the Scots derives from the ancient Gaelic name Eibhear as well as from the Old Norse original. The Welsh, on the other hand, also regard Ivor as a variant form of Ifor, meaning ''lord.''
