Christopher's years were defined by courage in the face of daunting illness. Diagnosed with skin cancer and Osgood-Schlatter disease - an illness which can cause painful inflammation in the knees of young athletes - Christopher nevertheless loved to play sports and "roughhouse and wrestle with his Daddy" and his brother and sister, according to a statement issued by the family.
"He was greatly loved by all who knew him," the family said. "He never met a stranger. You were always a friend in his eyes."
Emily loved unicorns, Lady Gaga and dreamed of one day traveling to Paris to become a fashion designer.
The third-grader died at Plaza Towers Elementary with seven other children, including her best friend Antonia Candelaria, in Monday's tornado that tore through a part of Moore.
Emily "rode up to heaven on a unicorn traveling on a path of love leaving Moore," her family wrote in her obituary. She was a beautiful princess, her family wrote, with a love for "all things girly."
CBS News' Mark Strassmann spoke with the family about their loss.
"It's like taking a piece out of my heart and just like stomping on it," said her grandmother, Yolanda Hornsby.
Karrina was not quite old enough to be at school like her two older siblings, so she was at home huddled in a bathtub with her mother, younger sister and grandmother.
The tornado threw the women and children in different directions and her parents could not find Karrina that night. It was only later that they learned that searchers had found Karrina's body in the rubble of what had been a neighbor's house.
Her father, Phillip Vargyas, said Karrina "had a smile that would light up the room."
Just 7 months old, Sydnee had crawled for the first time on Sunday. The strong winds pulled Sydnee out of her mother's grasp while they huddled together in a bathtub.
When the debris stopped swirling, Laurinda Vargyas said she found Sydnee on a driveway.
"She was just laying there helpless. All I could do was sit there and hold her. She was already gone," Laurinda Vargyas told The Oklahoman newspaper. "They say she didn't suffer. So I've got to find peace with that."
Antonia loved to sing. She knew the words to most of the songs on the country radio station her family frequently had on and she would sing along, bringing joy to the house.
In an obituary, the family remembered the "gentle and loving spirit" of a girl with a sweet nickname, "ladybug," that complimented those of her two sisters, who are affectionately called "butterfly" and "dragonfly."
