Four women who met online and quickly became close friends have discovered they are actually sisters, separated at birth. The women, all in their 30s, are now sharing their incredible story of sisterhood with the world.

The story began when Amanda Dunford, a 35-year-old from Texas, joined a Facebook group for people interested in genealogy. There, she came across a woman named Debra Biagini, who bore a striking resemblance to her. The two started chatting and quickly became friends.

Soon, two other women joined the group, also bearing a resemblance to Amanda and Debra. Christiana Gionet, 33, from New Jersey, and Karyn Skelton, 34, from Wisconsin, were soon welcomed into the fold.

The four women hit it off immediately, sharing stories about their lives, their families, and their interests. They even joked that they looked like sisters. But it wasn’t until Amanda submitted her DNA to Ancestry.com that the group’s suspicions were confirmed.

“I was so excited to finally see my ethnicity breakdown,” Amanda told Good Morning America. “But when I saw a woman in the ‘close family’ section, I freaked out.” The woman turned out to be her biological sister, Debra.

Over the next few weeks, the women worked with a genealogist to piece together their family tree. They discovered that they were all born to the same mother, who had given them up for adoption separately. The sisters were shocked but overjoyed at the news.

“I never thought I would find my family,” Karyn said. “I just thought I would have to accept that I was alone in this world.” Now, she and her three sisters are making up for lost time, talking on the phone and video chatting every day.

The women recently met in person for the first time at a hotel in Texas. They shared tears and hugs as they finally embraced each other as sisters. “It was like looking in the mirror,” Debra said. “We all had the same mannerisms and laughed the same way.”

The sisters are now planning to track down their birth mother, who they hope is still alive. They also hope that their story will inspire others who were adopted to search for their biological families.

“We want to show people that there’s always hope,” Christiana said. “You never know what can happen when you start searching for your roots.”

The women’s story has gone viral on social media, with thousands of people sharing their joy and excitement. Many have praised the power of technology to bring people together and reunite families.

The four sisters say they are grateful for the chance to have found each other and plan to continue their close bond for the rest of their lives. “We’re not just friends,” Amanda said. “We’re sisters. And nothing can ever change that.”
