Meaning: Its source is Andreas, a Greek name meaning "Manly."

Popularity: The name Andera ranked 3666th in popularity for females of all ages in a sample of the 1990 US Census.

Though this name appears on the 1990 U.S. Census lists, it is used by only a small percentage of the general population.

Narrative: There is some dispute about the origin of Andrea as a feminine name, which only made its appearance among English speakers in the 17th century.

It may have been developed by the Scots directly from the English Andrew, the name of their patron saint, without reference to the Greek Andreas. Or it may have been derived independently from the Greek vocabulary word andreia (meaning ''manly'' or ''warrior'') that is the common ancestor of all these names.

Whatever its origins, it has enjoyed wide popularity among all English speakers in the 20th century.
