About Unknown
Unknown was given to nearly 80 American babies in a recent year, but we can only hope they won't stay as such. Like Baby, Babyboy, and Infantmale, Unknown is probably used as a placeholder by parents who need to register their baby but haven't decided on a given name yet, whether because of cultural naming traditions or because of indecision.

Given to nearly 80 babies in the US in a recent year, different cultural naming traditions or simple indecision are hopefully the reasons behind this figure.
