WATCH: Lifelong best friends discover they're actually brothers Loop News Created : 27 December 2017 World News Two Hawaii men who grew up as best friends recently learned that they're actually brothers - and revealed the surprise to family and friends over the holidays. Alan Robinson and Walter MacFarlane have been friends for 60 years. Born in Hawaii 15 months apart, they met in the sixth grade and played football together at a Honolulu prep school. MacFarlane never knew his father, and Robinson was adopted. Separately, they sought answers about their ancestry. MacFarlane turned to family history and DNA-matching websites after unsuccessful searches on the internet and social media, Honolulu news station KHON-TV reported . A top match - someone with identical X chromosomes - had the username Robi737. Robinson's nickname was Robi and he flew 737s for Aloha Airlines. It turned out Robinson used the same website to find answers about his family. They later learned they have the same birth mother. They revealed the relationship to friends and family during a party on Saturday night. They have plans to travel and enjoy retirement together.
