CENTRAL ILLINOIS -- Rorie Joslin, 3, was diagnosed with a rare form of Leukemia last November.
Doctors said finding a Bone Marrow donor by March was vital in keeping her alive.
However, since, family members say Rorie's spark has been unbreakable.
"She has been such a fighter. She has not gone according to plan, at all," said Rorie's aunt, Charisa Ausfahl. "She has beaten so many odds. She is still, at this stage, spunky and full of personality. That is pretty unheard of."
Ausfahl, who lives in Bloomington, has been involved in setting up multiple Bone Marrow Match Drives throughout Central Illinois.
Now, all the hard work has paid off.
"We got the news last week that it had been narrowed down to one and the doctors were choosing to go with that one," said Ausfahl. "It was just elation all over the U.S. because we have family everywhere."
After thousands across the country have given a few swabs of the mouth to help little Rorie, one 20-year-old man has been selected as a 5 out of 6 donor, with 6 out of 6 being a perfect match.
The anonymous donor has passed a blood test and will go through some final physicals.
Rorie is expected to undergo the transplant in 4 to 6 weeks, if all goes as planned.
"She is so not out of the woods yet," said Ausfahl. "Her body has to accept his bone marrow. He would forever be our angel."
