Only Sort of An Only Child

ABC News shares the story of a Bay Area woman who was raised as an only child, but recently learned that she shares a biological father with dozens of other individuals.

Shauna Harrison took a crack at 23andMe DNA testing to find out more about her health and disease susceptibility after learning that she had an unknown biological donor dad, the piece reports. Through her 23andMe profile, Harrison discovered that she has the same bio-dad as at least 29 others, including some individuals who "only learned they had a different biological father after they got the [23andMe] results."

While some siblings "have chosen to remain anonymous," Anser Hassan writes, others have started connecting in person or through a Facebook group where the siblings can find "a spreadsheet to keep track of birthdays and a welcome packet for new family members."
