REUNITED BY SCIENCE

Millions of people have used commercial DNA tests to trace their family trees. For a few lucky folks, the results have been lifechanging, introducing them to relatives they had lost long ago—or never knew existed.

BOND OF BROTHERS

Walter Macfarlane, 76, and Alan Robinson, 74, have been friends for more than 60 years. They grew up a few miles away from each other in Honolulu, Hawaii, and met at school, where they played American football together. They are so close, they’re Uncle Walter and Uncle Alan to each other’s kids. So imagine their surprise when they discovered they were in fact biological brothers.

“It did feel natural,” Walter says of the revelation. “We knew each other so well.”

It came about, as so often happens, by accident. Walter, a retired maths and physical education teacher, knew that he had a complicated family tree. His mother had been young and unmarried when she gave birth to him during the Second World War, and because she couldn’t raise him on her own, the family pretended that his grandmother was his mother and his mother was his sister. Walter didn’t learn the truth until he graduated from high school. Even then, his mother never told him (or anyone else) who his father was.

So in 2016, when commercial DNA-testing kits were starting to take off, Walter’s daughter, Cindy Macfarlane-Flores, suggested he try a couple. When Cindy logged on to ancestry.com to check the results, she saw that a user named Robby737 and her dad shared enough DNA to be half siblings. When Cindy asked her parents whether they knew anyone who could have that username, her mother immediately thought of Walter’s friend, Uncle Alan. His nickname was Robby, and he used to fly 737s for Aloha Airlines.

Could that really be possible? Walter wondered. He spent ten minutes trying to get his friend on the phone. When Alan finally answered, he confirmed to Walter that his username was Robby737.
