For many years, Sheena Holland-Dolan, thought she was the only child. She discovered that she had 77 secret siblings.
Her mum and dad had used a sperm donor after they struggled to conceive.
“To say it was a shock was an understatement,” she told MailOnline. “I was left shaken.”
She used 23andme.com website from which she discovered that she was the 47th of the same father.
Her biological father had become a sperm donor while in college in order to earn some extra cash.
“It does worry me slightly that if I go on to have children, I will have to warn them that they need to be very careful when choosing their partners,” she confessed. “They will have so many close relatives out there who they will know nothing about.”
But she added: “I’d love to meet all of my half-siblings, eventually.”
