Greek
LACHONEUS is the masculine from of the hypothetical Greek word *lakonios, "Spartan, Laconian"; cf. the attested forms lakonion (neuter) and lakonia (feminie). Further, the "ch" suggests that the "k/c" stop sound has undergone intervocalic spirantization (see Gesenius/Kautsch/Cowley, Grammar of the Biblical Hebrew).
(Book of Mormon Onomasticon 2015)
Lachoneus1 was the chief judge and governor over the Nephites. He was governor when the Gaddianton robbers reached a level of power to challenge the government. Lachoneus1 was described as “a just man, and could not be frightened” and “so great and marvelous were the words and prophecies of Lachoneus that they did cause fear to come upon all the people” (3 Nephi 1-6). He organized the Nephites militarily against the Gaddianton robbers, and organized the people to gather in one fortified body to withstand the Gaddianton robbers, which they did, after a number of years defeating the Gaddianton robbers and establishing peace in the land.
Lachoneus2 was a judge and son of Lachoneus1 and governor of the Nephites. It is implied that he was a just man, opposing the under-judges who were putting righteous people to death without legal authority. These underjudges formed secret combinations and plotted and successfully assassinated Lachoneus2 while occupying the judgment-seat (3 Nephi 6-7).
