CENTERVILLE — Isaiah Jerome Jones was supposed to have a long life, but instead he will have a legacy. After 7-month-old Isaiah died and his donated organs saved the lives of two other children, his aunt signed up to be a donor. So did a cousin who just earned her driver’s license. And there will be those touched by the image of the chubby-faced boy with the cowlick on the Donate Life Rose Bowl float. Tim and Leighann Jones hope others will be inspired to sign donor cards.
