Lyndal Bubke grew up thinking she only had one sibling, but when she did an ancestry test online, she discovered she actually has 77 siblings and there could be even more. Lyndal is an IVF baby, conceived with the help of a sperm donor at Queensland Fertility Group. "The donor donated 325 times and they kept using that sperm for years and years and years," she tells A Current Affair. She estimates the actual number of siblings she has could be between 250 and 350, created through different clinics.
