reindexing death indexes but they missed one

I received a batch of the death indexing that someone had put all the names , 118 of them, but not any of the other information. Near the beginning (the 13th one) there was a name left out. Is there a way to insert a new person without having to delete all the other names ? I had this happen previously but it was the 4th from the end so i just redid the last 4. Id rather not have to delete and reenter the next 100. Thanks
