The name Jerrica is a relatively modern variation of the feminine given name Erica, which is derived from the Germanic name Airika. The Germanic roots of Airika are thought to be derived from the Proto-Germanic words *aiz (honor, respect) and *rīkaz (ruler, powerful).

The earliest known use of the name Erica dates back to the 7th century, with records showing individuals bearing the name in parts of what is now Germany and the Netherlands. Over time, the spelling evolved from Airika to Erica as it spread across Europe.

While the name Erica has been in use for centuries, the variant spelling Jerrica is much more recent, likely emerging in the late 20th century as a creative respelling or combination of Erica with other names like Jenna or Jeremiah. The earliest recorded instances of Jerrica as a distinct name are difficult to pinpoint, but it appears to have gained popularity in English-speaking countries like the United States and United Kingdom in the latter half of the 20th century.

One of the earliest notable individuals with the name Jerrica was Jerrica Linn Benton, a fictional character and the alter ego of the pop star Jem from the 1980s animated series Jem and the Holograms. While not a real person, Jerrica Benton's prominence in the popular children's series likely contributed to the name's increased use.

Other noteworthy people named Jerrica include:

1. Jerrica Tsai (born 1986), an American model and television personality.
2. Jerrica Patton (born 1986), an American basketball player who played professionally in the WNBA.
3. Jerrica Benton (born 1992), an American singer and songwriter.
4. Jerrica Farrington (born 1995), an American track and field athlete who competed in the 2016 Summer Olympics.
5. Jerrica Little (born 1998), an American professional soccer player.

While not an ancient name by any means, Jerrica has gained a foothold as a distinct feminine given name, particularly in the United States, over the past few decades. Its roots can be traced back to the Germanic Airika, but its modern spelling and popularity are relatively recent developments.
