The name Brionna is a modern variation of the feminine given name Briana, which has its origins in the Celtic language of ancient Britain. The name Briana is derived from the old Celtic word "brig," meaning "high" or "exalted." It is believed to have emerged as a name during the Middle Ages, when Celtic culture and language were still prevalent in parts of the British Isles.

While the name Briana has a long history, the specific variant Brionna is a more recent development, likely emerging in the late 20th century as a creative spelling or adaptation of the traditional name. There are no known historical references or records of the name Brionna itself being used in ancient texts or religious scriptures.

One of the earliest recorded uses of the name Brionna can be found in the 20th century. Brionna Goff, an American actress and singer, was born in 1990 and has appeared in various television shows and films. Another notable person with this name is Brionna Jones, an American professional basketball player who was born in 1995 and currently plays for the Connecticut Sun in the WNBA.

In the world of literature, Brionna is the name of a character in the fantasy novel series "The Chronicles of Narnia" by C.S. Lewis. The character, Brionna the Centauress, appears in the book "The Silver Chair," published in 1953.

Brionna Paschal, an American singer and songwriter, was born in 1994 and has released several singles and an extended play (EP) album. Additionally, Brionna Hairston, an American track and field athlete specializing in the long jump, was born in 1997 and has competed in various national and international competitions.

While the name Brionna may be relatively new, its Celtic roots and connection to the traditional name Briana give it a sense of historical significance and cultural richness, even if specific historical records of its usage are limited.
