Sj

Sj is a boy's baby name of uncertain origin, recorded in U.S. birth data as an extremely rare given name. It may function as an abbreviated form of names beginning with those initials, or as a minimalist, contemporary name choice in its own right.

With 42 recorded U.S. births, Sj is among the shortest and rarest names in the country — a genuinely unique choice for parents who value radical brevity and individuality.
