Jacorius is of Latin origin, derived from the Roman family name 'Iacobus', which is itself drawn from the Hebrew name 'Jacob'. It means 'supplanter' or 'held by the heel', a reference to the biblical story of Jacob wrestling with an angel and being touched on the hip. The name Jacorius was likely used during the Middle Ages, as Latin influence waned and new variations of classical names emerged.
"Jacorius peaked in popularity between 1996 and 2000 with six births each year, but has since declined to five births every three years."
