Meaning and history
From an English surname that was derived from the given name Aveline. In the 17th century when it was first used as a given name it was more common for boys, but it is now regarded as almost entirely feminine, probably in part because of its similarity to Eve and Evelina. This name was popular throughout the English-speaking world in the early 20th century. It staged a comeback in the early 21st century, returning to the American top ten in 2017.
