Go-before
"Go-before" was a slang term of the Novans on the planet Terra Nova in the 22nd century. It was their word for their ancestors. They also referred as "before-family" to their go-befores.

Prior to contact with  in 2151, the Novans believed the go-befores were "gutted" by Humans when they lived on the overside. 

Later, one of the Novans, Nadet, came to believe that the go-befores and Humans were on the same shared path. Her mother, Vera Fuller, was both a Human and a go-before. She was convinced that her people should listen to the crew of Enterprise, who were there to help the Novans. ()
