Tessica is of Latin origin, derived from the feminine form of the name Anastasius, which means "resurrection". It is a variant spelling of the more common Jessica, and shares its popularity during the late 20th century due to the character Jessica Wakefield in the Sweet Valley series by Francine Pascal. Tessica peaked at its highest popularity in the United States in the early 1980s, ranking as high as #356 for girls born that year. Despite its relatively short period of popularity, it has remained a unique and distinctive name choice among parents looking for an uncommon yet appealing option for their daughters.
"The name Tessica experienced a notable peak in popularity during the early 80s, with a significant increase from 13 births in 1982 to 20 births in 1983. This trend continued until 1985, after which it began to decline steadily. Interestingly, there was a sudden spike again in 1991 with 16 births, but overall, the name's popularity has been on a downward trajectory since its peak."
