Etymology[]
Edgar's Name page says: [1]
"Selina is an Anglicized form of the French Celine, short for Marcelline, a feminine form of Marcel, the French form of Marcullus, an elaboration of Marcus, from Marticos, which probably refers to Mars, the Roman god of war.
-and-
Selina is also an alternate spelling of the name Selena. Selena is the Latin form of a Greek name, Selene, meaning “Moon.” It was another name for the Greek goddess Artemis." (Vaudree (talk) 00:00, November 18, 2015 (UTC))
