Rochester, N.Y. - Family heritage may be something some take for granted, but for Olha Duerr-Clark, it means everything.
“I miss her and wish I was there for her because she's 22 years old, and I don't know what she's gone through,” Clark said.
At age seven, Clark's mother passed away.
Five children was too much for Clark's father to take care of, so a woman in New Jersey agreed to care for the girls until they were older; but that too became too much.
“She didn't want the two oldest sisters, so she sent them back to an orphanage in the Ukraine,” Clark said.
Eventually Clarke was sent to another family in New York, leaving her youngest sister behind.
Ever since, Clark has started her search for her siblings.
“It's been tough because you can see how hard it is for her to know that she has a younger sister out there to know she couldn't be there for her, Olha’s husband, Kevin Duerr-Clark said.
Clark found her baby sister six years ago on My Space, but they never met and eventually lost touch.
Meanwhile, Clark reconnected with her other siblings who found her with the help of a Russian TV station.
They met last year.
“That was great,” Clark said. “I was able to see my two sisters, and my brother and their kids because it's always been a mystery.”
While no one has heard from or seen their youngest sibling, Clark still holds out hope.
“I hope my sister reaches out to me, even if she doesn't' want to keep in touch,” Clark said. “I want her to say yes or no, it's hard for me to guess and not know.”
Clark says she believes her youngest sister is somewhere in the U.S.
Clark and her husband say they plan to hire a private investigator to help with their search.
