Jerri is of American origin, derived from the English name Geraldine, which means 'ruler with a spear'. It is often used as a pet form of Geraldine but can also stand alone as an independent given name. Jerri gained popularity in the mid-20th century and has been used consistently since then.
"Jerri was quite popular as a name for girls born between the years 1943 and 2009, with over 270 instances recorded during this period."
