When Courtney McKinney was 16 years old, she learned that she’d been conceived through anonymous sperm donation.  As an adult, Courtney discovered she had a half-sister: Alexandra Sanchez.

Theirs is one of the many families that have expanded as a result of online DNA testing.

At StoryCorps, Courtney told Alex how she’d set out looking for her father, and about the moment she found a sister instead.
