Three Siblings Abandoned As Newborns By Same Mom At Separate Times Meet For First Time

A woman's search for her biological parents led to finding a brother and sister.

— -- It was early morning in 1981, when a young woman in Lawndale, California, called police to report discovering a baby in a paper grocery bag next to a dumpster in a nearby alley.

The baby, Janet Barnicoat, was eventually adopted and grew up about 100 miles from that alley.

Barnicoat said she always knew she was adopted but didn't learn the story about her past until around the time she entered junior high school.

"I got really mad and angry [at my birth mother], and I held onto that for quite a long time," Barnicoat told ABC News' "20/20." "How do you leave your child in a paper bag in an alleyway? It felt like, you know, she tossed me away. You put me next to a dumpster. It was tearing me up inside."

"There was questions of, 'Do I have siblings? Who are my parents? Why was I adopted? Why didn't they want me?'" Barnicoat added.

As she got older, Barnicoat joined the navy, became a partner in her father's barbershop and later had a family of her own. But as a mother to her five children, Barnicoat said she found it incomprehensible that someone could leave their child, only hours old, in an alley.

"Once having my own children, you know, you figure out what that natural, true love is. And I just couldn't understand how she didn't have that for me," Barnicoat said.

As an abandoned baby, or foundling, Barnicoat has no birth certificate and no idea who her birth parents were. So Barnicoat went searching for the woman who had called the police to report finding her by the dumpster, hoping she would have any clues about her past. She posted about her search for the Good Samaritan on Facebook and finally met her in 2013.

They became Facebook friends and agreed to stay in touch, but the woman offered no clues about Barnicoat's abandonment.

Hoping to find more answers, Barnicoat later sent a saliva sample to and almost immediately received a match.

"I was checking my email, and it said that I had a possible DNA match," Barnicoat recalled. "It said that, 'You have a DNA match, close family.'"

The match was with Dean Hundorf, who is Barnicoat's half-brother. Hundorf flew from his home in Lacrosse, Wisconsin, to meet Barnicoat for the first time at a terminal at Los Angeles International Airport in November 2014.

"It was like we had known each other forever and … like we never skipped a beat," Hundorf, 29, told "20/20."

"It was a brother hug, and going [30 years] without having any siblings, it was nice to have that connection and that bond," Barnicoat said. "For me, it was pretty much like we had never not been together, you know?"

But it turned out that Hundorf had also been abandoned as a newborn baby just days before Christmas in 1986.

"I said, 'I was abandoned at birth, and I don't have any information about any of my family.' And then that's when she said, well, you know, the same thing had happened to her," Hundorf said. "I'd imagine she did the same thing I did, was like, 'Whoa. What's going on?'"

Hundorf still had the umbilical cord attached when a man named Danny Huerta found him on his doorstep left in a paper bag. Huerta's house is just over a mile from the alley with the dumpster.

Like Barnicoat, Hundorf was adopted by a loving family, and he now works at a furniture company.

"I always, you know, was wondering, where I came from, who my parents were. I maybe tried to push it aside just to forget about it. But you know, it was always there," Hundorf said.

Barnicoat was shocked when she learned that what happened to her had also happened to her newly found half-brother.

"I think I got more angry at the situation when I found out about Dean," Barnicoat said.

CeCe Moore, a genetic genealogist whose specialty is abandoned babies, decided to help Barnicoat and Hundorf with their search for their mother.

In addition to, Moore crosschecked their DNA samples with the databases of and and found another half-sibling who shared a mother with Barnicoat and Hundorf.

"When you get a key like that, I mean that is just a godsend to have someone that close sharing that much DNA, and I thought, 'Fantastic, this is going to lead to one of their birth parents,'" Moore told "20/20."

However, the half-sibling didn't use their real name on the website so Moore tried to track them down using the sibling's unique username "Welfare Brand Cereal."

"We knew it was a female. Right away we found some other sites where she was using that username … It didn't give her name, but it gave her date of birth. And then we found her first name somewhere," Moore said. "So we had Julie, we had a date of birth, and I knew she was from California, so I went into the California Birth Index, put her first name and her date of birth. And someone came up."

Julie Hutchison, now 31, was also abandoned as a baby. According to newspaper reports, a delivery man discovered Julie wearing a blue jumpsuit at a market in California in January 1985. She was adopted and now works as an artist in Baltimore.

Like Barnicoat and Hundorf, Hutchison was found just hours old, umbilical cord still attached and wrapped in a towel. She also had the same questions about her past as her half-brother and half-sister did.

"I just want to know, you know, like how was their life growing up adopted? Did they have the same thoughts, you know, as I did growing up, like, 'Who was my mom? Who was my dad?'" Hutchison told "20/20."

Although they had different fathers, Barnicoat, Hundorf and Hutchison all had the same mother who abandoned them just hours after they were born at separate times over the years.

"20/20" arranged for Hutchison to meet her half-siblings for the first time, and the connection between the three of them was immediate.

"These three people were so much alike. They had the same sense of humor. They were cracking each other up," Moore said of the meeting. "There is something about biological and genetic bonds that survives any sort of separation."

As mysterious as finding each other for the first time was, it was even more shocking when the siblings finally learned who their mother was.
