Archeantus
From MormonWiki
Archeantus is a Nephites briefly mentioned in the Book of Mormon. In the Book of Moroni, Moroni copies a second letter that his father Mormon has written to him prior to being killed by the Lamanites. Among the first things Mormon tells his son is of several "choice men" who were killed by the Lamanites. Archeantus was one of these.[1]
