BOSTON (CBS) – Nerves mixed with excitement as a New Hampshire family waited for a miracle.

“Every emotion you could imagine,” said Aidan Barry. “Until they’re here I won’t relax.”

Two siblings from Ethiopia arrived at Logan Airport Tuesday to potentially save their brother’s life.

The two siblings are a bone marrow match for their 13-year-old brother Behaylu who was diagnosed with severe aplastic anemia earlier this year.

Behaylu was adopted seven years ago by Aidan and Midori Barry of New Hampshire.

When he was diagnosed with the rare disease, a charity swabbed his five siblings back in Ethiopia and his brother Rediat, 16, and his sister Eden, 9, were perfect matches.

“I’m so grateful they’re here,” said Midori. “It’s not the best circumstances but what an opportunity that we can see our son’s siblings here in America.”

Rediat and Eden had never been on a plane before. They’d never been out of their village.

New Hampshire’s U.S. Senators helped in speeding up passports for the two siblings, as did Ethiopia’s Ministry of Foreign Affairs.

The children will be in the United States for about a month before they head back to Africa.

Tomorrow the family will meet with the transplant doctors and the team will decide which sibling should undergo the transplant.

It’s hoped the transplant process will begin in two weeks.

Meantime, Behaylu and his two siblings have some time to reconnect before the transplant process begins.

Behaylu says he plans to take his brother and sister to play miniature golf and to see the beach because they have never seen the ocean before.
