Dr. Don Cline was a fertility doctor who used his own sperm to inseminate patients without their consent, according to the Netflix documentary, “Our Father.” Jacoba Ballard began unraveling the truth of her ancestry and her siblings with a DNA test.
Cline fathered at least 94 biological children, according to the documentary, but the exact number of children conceived is impossible to know. Ballard took a 23andMe test in 2014, and learned she had seven half-siblings. She contacted the siblings to learn about their mysterious familial connection, and realized each of the mothers had seen the same fertility doctor.
As many more siblings began taking DNA tests, their information was added to the database and the number of siblings in the count grew. Each time a new connection was added to the database, Ballard prepared to break the news, she said on the documentary.
