In 2018, 2 is the most common age for an American (U.S.) Delilah who is registered female with the Social Security Administration. It is the 1, 554th most common female first name for living U.S. citizens.

Delilah seems to be a controversial name, but in fact it was favoured by the (deeply religious) Puritans in the 17th Century. The Biblical character was treacherous, but also a beauty and intelligent, which may be why they adopted her name.
