NEWTON, Kan. -

A Newton couple has one very special reason for you to sign up to become a bone marrow donor. Her name is Sydney.

She's a 9-year-old girl who lives in Michigan. Her grandma says she loves soccer and crafts and yes, even school. Her grandpa describes her as lovable, but often teases him. They both say she could lose her battle with Leukemia if she doesn't find a donor.

"Hate to say is but, bone marrow is probably the only thing that's going to save her life," said Fran Balzer, Sydney's grandpa who lives in Newton. "So it's very important."

The two held a bone marrow registry event in Newton Saturday where they said hundreds showed up to see if they were a match.

"Lots of them don't even know us," said Fran.

His wife Jacquie said they are looking for a hero for their granddaughter, but even if the donor isn't her match, they could be someone's match.

"They're going to be a hero to whoever they are able to help," said Jacquie.

Sydney's battle with Leukemia started when she was 6.

"We've already been through all of this once," said Jacquie. "And now she's 9 and going through it all again. She's very strong, but this is very hard. It was kind of devastating this time because in February we go the OK that she was completely cured. Then at the end of August we saw that she had relapsed."

None of her family members are a match for Sydney, so they are reaching out to communities to find one.

"It means life or death, especially for Sydney," said her grandpa.

A registration event is schedule for Tuesday November 19th in Wichita at the Asbury Church at 2801 W 15th St. The event goes from 10 a.m. till 7 p.m.

  • at least 4'10'' and 110 lbs
