Imagine growing up an only child and then when you’re well into adulthood, finding out that you have siblings! Lots of them!

That’s what happened to one San Francisco woman after she took a DNA test and now she may not be able to answer how many siblings she has. “And I am like, uh, no, yeah, umm, yes. (Laughs) About 29 of them” Shauna Harrison said.

At age 27 Shauna learned her dad wasn’t her biological father so she set out seeking answers.

She tried the ancestry site 23andme and found out the donor was Jewish of Russian descent, now 41 she went back to the site two years ago after learning about some advancements to DNA science.

“Boom. Next day I get an email from one of the siblings. Hey, looks like we are related. Not sure if that’s a surprise to you.” Harrison said.

Two and a half years later, and the family keeps growing now there is a total of 30 brothers and sisters.

Harrison says there is a Facebook page for the siblings, a spreadsheet to keep track of birthdays, and a welcome packet for new family members and she’s ready to welcome in more family members.
