Southfield, Michigan - Jaime Hall's search for her biological father led to a wild discovery: not only does she have at least five half siblings, her biological father may have fathered hundreds of children.

In 2008, the 61-year-old learned that the man who had raised her was not her biological father.

According to The Sun, Jaime was told that her biological dad was a family friend who had donated his sperm to help her parents. Jaime even ended up befriending the man, but then she got the results of her DNA test back – they didn't match with his.

Jamie wanted to know more, so she sent her DNA samples into two websites that do genetic testing. To her astonishment, she found out that she has five half-siblings who were also searching for their genetic roots.

Further research revealed that all of her half siblings were born in the same hospital that they all had the same delivering physician listed on their birth certificates: Dr. Philip Peven.

Dr. Peven was also her parents' doctor when they were trying to conceive. Jaime started to think that her parents' doctor wasn't just the one who had delivered her. She and one of her half-siblings decided to meet Dr. Peven and find out more.

While talking to Jaime and her half-sister, Dr. Peven admitted that he donated sperm as a student and while he was practicing. He also knew which samples he was using to inseminate his patients.

"There's a group of hospital doctors that donated sperm and when he couldn't get hold of a proper doctor - one that he liked – I think he had used his own sperm," Jaime told The Sun.

Jaime said that her parents had brought in the friend's sample, but that Dr. Peven decided not to use it. "He admitted he discarded the donor and when I asked why, he said it wasn't tested. He said he knew that if I kept it to himself and the other doctors, they knew it was viable, so they didn't have to worry about it."

As fate would have it, Jaime's older sister Lynn (63) is the biological daughter of another doctor at the same hospital.

Lynn and Jaime have no problem with their real linage or their origin stories. Quite the opposite, in fact they are grateful. "These women, my mother included, came to him desperate, and he gave them something that they all wanted."

During their conversation, Jaime expressed these feelings to Dr. Peven: "We said ‘you not only delivered us… we want to thank you for fathering us. Without you, we wouldn’t be here.'"

Peven, who is now 104, studied medicine in Chicago and worked in Detroit for many years, his own daughter Kari said that she had no idea how many children he fathered over his lifetime.
