Unfortunately, each friend learned that they were not a match.
As the chances appeared even slimmer, the couple received the unexpected news that Caitlyn was indeed a match.
"It's like hitting the lottery," said transplant surgeon Dr. David Cronin. "Practically speaking," he said, patients like Jonathan have almost no chance of finding a matching donor.
After undergoing more tests, the couple went into surgery last Tuesday at Baylor Medical Center in Dallas.
The couple are both at home recuperating and planning exciting activities for their new future together.
"Swimming and jumping and running and playing basketball," is first on the list, Caitlin said.
Jonathan and Caitlyn are looking forward to starting a family together, something they thought they would never have the opportunity to experience.
"That was on the back burner until all this came together," the couple said.
The newlyweds finished seminary school. Jonathan would like to pursue ministry overseas while Caitlyn studied musical therapy and would like to incorporate it into her ministry.
"A lot of our story has been shaped by suffering," Jonathan said, "So we want to work with other people who are suffering."
