Transcript for Twin Sisters Separated at Birth Reunite
everybody, and we have such a wonderful audience with us this morning. Thank you guys for joining us this morning. We do. Did you notice the twins that we have? We didn't plant them for this next story because we do have -- there they are. I hope people know you're here and you're not skipping work or anything like that. We do have an incredible story, Michael. What if one day you woke up and found out you had a twin. Two 10-year-old girls got the surprise of a lifetime when they discovered they had a twin sister living across the country. Audrey and Gracie separated at birth. Now, they are about to meet in person for the first time. Amazing. What do you say we take a look at the story first. Let's take a look. Reporter: A story of two families, miles apart with the same dream, to adopt a new baby. Jennifer and Thomas Doering of Wisconsin, already the parents of three boys. Just felt like we weren't complete. Really would love to have a daughter and finally decided to go through adoption. Reporter: Meanwhile, in Washington state, Nicole rainsberry and her husband Scott also hoping to expand their family. I've always thought about adoption. After we had our surprise third child, we decided to have a fourth and adoption seemed like a great way to add to our family. Reporter: Both families looking abroad for their future child, even open to taking a child with special needs. Their search leading them both to China. In July 2007 the rainsberrys uniting with their daughter Gracie who has a heart condition. It was pretty overwhelming to find out that, yeah, she was really sick. Reporter: The doerings meeting their daughter Audrey 15 months old in August of 2007 who also coincidentally has a heart condition. We knew he was small and frail and told us at 15 months she didn't walk yet. Reporter: They arrived in the U.S. With their new families, Gracie rainsberry undergoing two heart surgeries and Audrey Doering, one. Last month, Jennifer becomes curious about daughter Audrey's past. With the help of a Chinese researcher she discovers this photo. It shows Audrey on her Chinese foster mother's knee with another baby who looks just like her. It was unbelievable. I'm like, how -- I mean, this is stuff you read about and how could it really be that there are two of then. As soon as I had that picture I was desperate to find out who that other child was. Reporter: Jennifer with the help of Facebook eventually finds Nicole rainsberry and little Gracie. It's the craziest thing in the whole wild world to look at your child exactly. I mean everything was the same, the same hair, the same glasses, the same outfits and that was the moment I knew that they were -- they were the same. It was so crazy to be looking at what looked like Gracie but knowing that it wasn't Gracie. Right. Yeah, it's just surreal. I mean it's hard to process that information. Reporter: Now the twin girls coming face-to-face for the first time. I don't know how you are where you're watching this but the excitement and the tension, but before we get to the big reveal we'll welcome half 69 twins Audrey Doering with her parents Jennifer and Tom. Please welcome them. Oh, are you all right? Are you all right? Are you all right? We're going to get to the big -- hey, Jennifer, this is all because of you. You wanted to give your daughter a special Christmas gift. I did. Tell us about that. I was essentially looking for a little history for her for Christmas. I found a lost and found for Chinese children. We were able to locate that and then from there we were able to find an unseen picture that was given to us and from there that's when we determined that there were two when I opened the picture, two kids. Two audreys. There aren't two audreys but there are two of them. Audrey, for you, did you know you were getting a sister for Christmas? No. And I know, Tom, Audrey, you have three older brothers. Yes, I do. They're all very protective. How do you think Audrey felt when she found out she had a sister. Oh, I think every girl wants to have a sister so she was happy but I think the initial thing made her nervous, the whole -- overwhelmed is the word she likes to use so took her basically a day to start trying to talk about it more. Audrey, are you ready? Yeah. You want to do this? Yeah. Come on. Come over here. And stand right here, okay. Are you ready? I'm going to back away. I don't want to get into this moment. All right, Gracie, come on out and meet your sister. Hey there. Come on. Hi there. You remember talking that first day on the phone? You guys do look alike. All right, guys. You guys are doing good. Come on over. All sit down over here. Oh. Wherever you like. Here we go. I can't tell who is who now. I know. Okay. Can I just touch you? Oh. You're doing good, Gracie. So, Audrey and Gracie, we're so happy -- I don't -- I'm at a loss for words. This is overwhelming for me because I'm a father of twin girls who are 12 years old and how are you two feeling? Your first impressions of seeing your sister? Excited. Happy. Yes. It's very overwhelming. It truly is and, Nicole, how did you feel when you were contacted. Yeah. And that had to be something for the family to digest and determine how to move forward. How did you go about it? Boy, yeah, it was shocking to say the least. You know, we've been a family for over nine years and to all of a sudden find out that there's this missing piece of her life that is so incredible. It was, yeah, just crazy. We've been talking about these adorable twins but also for you, mom and dads, it's a moment -- We have more family. It's a family, yeah. Audrey, we said you had three older brothers. How does it feel to have your sister now? I like it. I finally have like -- it felt like there was something missing so it was like -- it's complete. It's complete. And you all have been so wonderful and sharing this and also with working with Dr. Nancy Segal. She works with twin studies, psychology and has been really working with both families because this is a lot. This is an adjustment and you were okay with them coming on TV and doing it like this. We want to make everybody sure that that was okay but just tell us how this changes the dynamics of both these families. Well, this is a very important meeting, the twin relationship, the twin bond is a very strong one and so I think it was very important that these girls meet at this particular point in time when they have their whole lives ahead of them and what this does is it really revises family relationships. When you think about it, Nicole is Gracie's mom, but what is she to Audrey and Jennifer is Audrey's mom and what is she to the other girl? So what are the brothers and sisters mean to each other from the different families? We don't have labels for these relationships. But I think that as the families progress, we will learn how they deal with one another and they will be better able to help other families in these situations. And this has been a day full of surprises and also you also did a DNA test and what did we find out from the DNA test. We found from the test that these girls are identical twins with 100% certainty. Good work. Yeah. We could tell. Hey, robin, Tom said if they're not then something's wrong. Did you all decide because you all have been able to facetime. How did you all decide what to wear? I mean you're matching already. Did that just happen or did you all get together and on facetime -- We facetimed. We facetimed. Looking good. They made a choice and wanted to match in today is all about firsts, right? And surprises so we got a little something for you if I can find it. Well, we want -- the first chance as sisters with your families and we want you both to have -- we know you both have a love for music. While you're here in New York City we got a little something for you. We'll send you to the Broadway musical "School of rock," all right? At the winter garden theater. Everybody is going. But then if you're going to do that you're hungry so you need a little food so planet Hollywood is going to feed everybody, the families are going to go there, planet Hollywood is going to take care of that. And you guys, you guys have talked about how you guys live far apart and you want to make sure that they can spend time together and I know there's been a go fund to help the travel and such. Is that true? Yes. Okay, we thought we'd help out with that too. Our friends at expedia.com gave us some tickets that you two can see each other and continue your bond as sisters. Thank you. Thank you. Nice. You guys can travel. Yes. All right. I tell you, this is amazing. So just wrap it up for us right now. What is in your heart right now, Gracie and Audrey? Love. Love.
