I should also note that you are making the assumption that a person who is truly ignorant of Jesus is by definition a reprobate.
If he were elect, God would make him truly desire to follow God with a sincere heart. Now, if he happened to be stuck on a backwards Pacific island with no missionaries and no contact with civilzation, he could very well remain ignorant of Jesus.

No. Allow me to speak for me.
A person who DIES truly ignorant of Jesus is by definition a reprobate and will JUSTLY suffer the penalty of his sin and sins.
