Kimm is of Scandinavian origin, derived from the Old Norse personal name Kimmi or Cimme. It means 'helmet' or 'protection', which could metaphorically translate to something like 'defender' or 'shield'. This name was initially more common in Scandinavia but has since gained international recognition.
"Kimm peaked in popularity between 1954 and 1955, with 13 and 18 births respectively, before tapering off to an average of around 7 births per year until 1960, with a notable dip in 1962."
