Isidore

Isabel and Isadora are back: could it now be time for a more widespread revival of Isidore?

A common ancient Greek name belonging to several saints--including Saint Isidore the Ploughman, patron saint of Madrid and the great encyclopedist St. Isidore of Seville, whose work formed the basis of much medieval knowledge--Isidore was adopted by Spanish Jews to the point where it was almost their exclusive property.

In addition to the obvious Izzy, another traditional nickname is Dore/Dory.
