The name Elin has its origins in the Old Norse language, tracing back to the Viking age in Scandinavia around the 8th to 11th centuries. It is derived from the Old Norse word "elin," which means "torch" or "shining light." The name was likely used to convey a sense of brightness and radiance.

In ancient Norse mythology, Elin was also the name of a valkyrie, one of the female figures who were believed to choose those who would be slain in battle and bring them to Valhalla. This association with a powerful mythological figure may have contributed to the name's popularity during the Viking era.

One of the earliest recorded instances of the name Elin can be found in the Icelandic Sagas, a collection of historical and literary works dating back to the 13th century. In these sagas, Elin is mentioned as the name of several notable women, indicating its widespread use in medieval Scandinavian societies.

Throughout history, several prominent individuals have borne the name Elin. One notable example is Elin Wägner (1882-1949), a Swedish writer, feminist, and activist who played a significant role in the women's suffrage movement in Sweden. Her works, such as "Åsa-Hanna" and "Väckarklocka," explored themes of gender equality and social justice.

Another well-known figure was Elin Danielson-Gambogi (1887-1964), a Finnish-American artist renowned for her portrait paintings and landscapes. She was part of the Woodstock Art Colony in New York and gained recognition for her stylistic blend of Impressionism and Realism.

In the realm of sports, Elin Nordegren (born 1980) is a Swedish former model and the ex-wife of professional golfer Tiger Woods. She garnered widespread media attention during her marriage and subsequent divorce from Woods.

Elin Pelin (1877-1949) was a prominent Bulgarian writer, known for his novels and short stories that depicted the lives of rural Bulgarians. His works, such as "Gera the Wolf" and "The Mighty Stremmas," are considered classics of Bulgarian literature.
