Alma 39

Upon teaching his son, Corianton, concerning the Savior, His atonement and gospel, he makes an interesting prophecy -

"...this was the ministry unto which ye were called, to declare these glad tidings unto this people, to prepare their minds; or rather that salvation might come unto them, that they may prepare the minds of their children to hear the word at the time of his coming."  (Alma 39:16)

This could easily mean, their children not yet born.  The Savior would come about a hundred years later.
