Walter Gordy was diagnosed with lymphoma nearly five years ago. Following treatment, the 37-year-old wanted to make sure he wasn't subjected to any other ailments, so he took a DNA test through 23andMe. What he discovered was that Mark Tolson, his friend of 12 years, was his half-brother.

"I grew up as an only child. I always wanted siblings," Gordy said on the Today show Wednesday morning.

Gordy's cancer came as a shock to him, as he admits he never had so much as a cold growing up. Fortunately, Gordy was pronounced cancer-free after nine months of treatment. That prompted him to find out more about his family lineage. While he was well-versed on his mother's side of the family, Gordy didn't know much about his father's side.

Tolson, also an only child, was interested in discovering his ancestry after the birth of his son. So he submitted his DNA to 23andMe at the same time as his friend. It was Tolson who made the connection.

"I saw a part that said DNA relatives, so I clicked on that," the Houston native said on Today. "It popped up and it said Walt Gordy III, and I said, 'Mom, I know him! I know him.'"

Gordy and Tolson's mothers revealed they used artificial insemination to get pregnant, and unbeknownst to them had the same donor. Like their sons, both women have been friends for years.

"We've always prayed that he would find that fraternal part of him," Gordy's mother, Booker Lynne Graves, said on the morning program. "And we truly look at it as a blessing from God because our prayers were answered. It's just a beautiful joy to both of them that they have one another the rest of their lives."

What a blessing indeed.
