Casper is actually the Dutch and Scandinavian form of Jasper, which means “treasurer” in Persian. And while most people might associate Jasper with its more recent namesakes like the character from Steven’s Universe, a vampire from the Twilight series, or an agent of S.H.I.E.L.D. called Jasper Sitwell, the name was assigned to one of the three wise men, who visited the baby Jesus. You won’t find names of the three kings/ wise men/ Magi in the bible, but you can find them within Judeo-Christian Legend. According to Western tradition, Caspar, also known as Gaspar, Gathaspa, or Jaspar, was an Indian scholar or sometimes a king of India. He is often portrayed as a young beardless man, who brought frankincense.

Variants of the name were commonly used in the English-speaking world during the Middle Ages and during the 1890s, Casper and Jasper saw a spike in popularity in the United States. Both, died off by the 1940s until Stephenie Meyer brought back the name Jasper in 2010. Although, I like to think that everyone was just super into naming their children after the gemstone instead of the vampire.


Variant: Caspar; Gaspar; Gathaspa; Gazsi; Jasper; Jesper; Kasper;

Agatha is the Latinized form of the Greek name Agathe, which is derived from the Greek word “agathos,” meaning “good.” If you’re looking to name a character born in the USA between 1880 and 1930, Agatha is a reasonable choice as it ranked in the census for popularity between those years.

Saint Agatha of Sicily is the Christian saint of breast cancer patients, wet nurses, bell-founders, and rape victims. She chose to live a life of celibacy as a consecrated virgin until a high-ranking official, Quintianus, decided he wanted her. She spurned his advances and he responded by tearing off her breasts off with pincers. She managed to survive that, and eventually died after more torture involving hot coals. Now, she is celebrated in Italy every February 5th with a delicious pastry that looks like a breast.

Saint Agatha’s name has been used throughout Christian Europe with various spellings, but the most famous barer of her name was the mystery writer, Agatha Christie. She created such characters as Hercule Poirot and Miss Marple. While she may have died at the age of 85 in 1976, she disappeared without a trace for ten days in 1926. Sir Arthur Conan Doyle even gave a spirit medium one of her gloves in the hopes of finding her. She turned up at a hospital with amnesia and her autobiography makes no reference to her disappearance.

Agatha is also the first name of Ms. Trunchbull, the primary antagonist of Ronald Dahl’s Matilda.
