It was DNA testing that proved the three were half-siblings. Keall adds that "the three of us are now spending time together and getting to know our new-found families and have committed to unite on our family search for our biological mother and fathers.""Around my 18th birthday, I felt compelled to start this search [for birth family]. Over a 20-year period, I had no success until, in the last few months, I found a biological half-brother named Kevin and a biological half-sister named Kathie Rennie. We were all abandoned in Prince Rupert over a 39-month period."
