DENVER (KDVR) -- At least 10 people have been left to believe they are half-siblings with the same donor they say is Dr. Paul Jones.
Three strangers with a similar curiosity took DNA tests with Ancestry.com or 23andMe. Their results traced back to one man.
Almost a dozen strangers across the country are related to a fertility doctor in Grand Junction and Women's Healthcare of Western Colorado.
The siblings say Jones helped their mothers conceive.
On Nov. 1, Jones voluntarily surrendered his medical license. He denies allegations that he used his own "fresh sperm" to impregnate multiple patients.
One family filed a lawsuit against Jones and Women's Healthcare of Western Colorado. Other siblings say they plan to do the same.
Jones did not respond to request for comment.
