Donna

Donna is Italian for "lady," and its use as a name in English-speaking countries only began in the 1920's. According to some sources it has been used as a feminine form of Donald--I'm guessing that this basically means daughters of men named Donald who wanted to name their children for themselves. Donna was a very popular name from the 1930's through the 1960's, making it as high as #8 in the 1960's. In fact, it was used so much that even though it is a relatively late addition to the name game, it now sounds rather common, and so has dropped in popularity, all the way into the 700's.
