Ivory was last popular a hundred years ago -- oddly, more for boys (à la Keenen Ivory Wayans) than girls. In 2013, it finally began to regain some momentum in the female rankings, reentering the Top 1000 as Number 866. 2015 saw it rise to Number 720. Word of caution, however - people may associate this name with illegal poaching of elephants and the ivory trade. Or, more prosaically, the popular brand of soap.
