These two guys have been pals for more than 60 years before discovering that they were actually brothers. Walter Macfarlane and Alan Robinson grew up together in Honolulu, Hawaii and went on vacations with their families as adults. The pair decided to research their family histories when they were already in their 70s, as neither were raised by their birth parents—Alan was adopted, and Walter did not know who his father was. After using a DNA website, though, the life-long friends found out that they shared a birth mother. Once the answers came, the duo realized why they shared such a deep bond.
