According to Michael Hobby, the fact that the Mulekites were deeply involved in Jaredite culture is obvious . . . the fact that they spoke the Jaredite tongue is evidenced by their personal and city names, names of coinage, etc. One direct example is the name Korihor [Mulekite] in Alma 30:12. There is also a Corihor [Jaredite] mentioned in Ether 7:3-15, 13:17.
In all, as much as 30-40 percent of all Nephite/Mulekite names may have been Jaredite or contained one or more Jaredite elements. This could hardly have resulted from reading the record of a fallen people (see Mosiah 28:11-13). [Michael M. Hobby, The Mulekite Connection, pp. 21-22]
