Oliva

This name is not just a feminine name. My husband's father's middle name is Oliva. His grandfather (my husband's great-grandfather), in turn, was named Oliva as a first name. It was also the name the father of the Dionne Quintuplets. My husband's family is French Canadian (like the Dionnes) and so I'm guessing that Oliva has a French root.

Also, it seems Oliva is a surname of Spanish origin and the name of several towns in Spain, Navarre, Italy and Poland. There was also a famous abbot of this name from Catalonia in the 10th century.
