Baby Jade came into the world with all odds against her and left with a legacy that now defines her.  She lived for just 55 minutes. In that short lifetime, Jade touched hundreds of people with her story and her gifts of life-saving heart valves and tissue for healing and research.   Her mom and dad, Allison and Nick Townsend, learned at 26 weeks gestation that their first baby had an extra chromosome and would not survive long after her birth — if she made it that far.
