The last time the Chrisman siblings saw their baby sister, the family was reeling from the death of their mother, and their father was struggling in the throes of the Great Depression.
Put up for adoption to relieve the pressure on her family, Barbara Miller spent decades searching for her biological relatives. She was unaware that she had eight brothers and sisters looking for her at the same time.
"It was fabulous, just like we never parted," Barbara, now 82, said of meeting her three sisters and one brother. "We just talked and talked."
"I got some one-on-one time with each one of them," she said.
It was a meeting Barbara never expected. It wasn't until about six weeks ago that she knew she had brothers and sisters. Even after learning their names from a 1930 census report dug up by relative, "I did not expect to find anyone still alive."
Instead, she hit the jackpot. The timing of the siblings reunion coincided with a family party to celebrate the 90th birthday of Exie Davis, the oldest surviving sibling. She also met Evelyn Cox, 87, and twin brother and sister Robert Darmon and Mary Long, both 85.
"We were just on cloud nine," Robert told ABCNews.com. Barbara, he said, shared "quite a lot of resemblance from my sister and another sister. We all have the same nose!"
The five siblings are the youngest of 12 children born to George and Dixie Lee Chrisman. Three of the children died in infancy.
By the late 1920s, the Kansas City family had fallen on hard times. Dixie Lee died at age 42 from liver troubles in 1928. Barbara said she has since seen a family photo of the entire family taken just before their biological mother died. One of the siblings, she said, remembered how Dixie Lee was so ill she had to be carried on a chair to pose for the picture.
By 1930, George Chrisman was struggling to provide for his family. A mail carrier noticed the father trying to raise nine children on his own and helped George get his youngest three into a home for children.
Robert and Mary were adopted together by the mail carrier and his wife who helped put them into foster care. Their names were changed from Glenn and Gladys. Barbara, then a toddler, was adopted by a separate couple, and her name changed from Lillian. She was raised as an only child in what she called a "difficult" home.
By the time World War II rolled around, the older Chrisman children had begun looking for their lost silbings.
Mary was contacted by Maurice Chrisman, their older brother. Maurice relayed information to Mary about her biological siblings before he left to serve with the Air Force in Japan, where he was killed three weeks before the war ended.
Even after Maurice Chrisman helped reconnect them with the rest of their brothers and sisters, Robert said they communicated only sporadically through the decades, meeting typically only to attend the funerals of the older children, most of whom died decades ago. His and Mary's parents, he said, discouraged contact with their biological families.
Just one state away in Oklahoma, Barbara was trying desperately to find clues about her birth family.
Her efforts, she said, were hampered by inaccurate information. She knew her original name was Lillian Chrisman, but had the wrong date of birth and was told her mother had been killed in a car accident.
