"She was insightful for her age and had a great sense of humor. She laughed a lot and always lit up a room including the people around her. She was very creative and was always drawing and designing things," her family said.
Olivia took art and dance lessons, played tennis, soccer and swam. She was involved in Girl Scouts and musical theater. She loved school and did well in math and reading.
Her family described her as a "grateful child ... never greedy." Each night, Olivia led grace at the dinner table.

Dylan Hockley, 6
"To know him was to love him," Dylan's grandmother told the Boston Herald about her grandson.
Dylan loved video games, jumping on a trampoline, watching movies and munching garlic bread, she said. He had dimples, blue eyes and "the most mischievous little grin," Theresa Moretti told the newspaper.
She said her daughter and son-in-law moved to Connecticut from England and chose to live where they did because of the schools. Dylan had an older brother.
"He was an angel," Moretti told the Herald. "And I think that's now why he's in heaven."
Dawn Lafferty Hochsprung, 47
Hochsprung, who became Sandy Hook Elementary School's principal two years ago, was "really nice and very fun, but she was also very much a tough lady in the right sort of sense," friend Tom Prunty said. And the students loved her. "Even little kids know when someone cares about them, and that was her," he said.
"I never saw her without a smile," said Aimee Seaver, the mother of a first-grader.
Hochsprung lived in Woodbury, Connecticut, with her husband, two daughters and three stepdaughters.
The longtime career educator majored in special education for her bachelor's and master's degrees in the 1990s and entered the Ph.D. program at Esteves School of Education at the Sage Colleges in New York last summer. Hochsprung led a school district's strategic planning panel and was the recipient of a national school grant.
Her accomplishments included overseeing the installation of a new security system requiring every visitor to ring the front entrance's doorbell after the school doors locked at 9:30 a.m.
"My mom, Dawn Hochsprung, was taken tragically from me. But she went down in a blaze of glory that truly represents who she was," her daughter, Cristina Hassinger, tweeted.
Madeleine Hsu, 6
Sweet. Unique. Bright. Determined. Sparking.
Those are words Madeleine's family used to describe their little girl.
"She was an avid reader who loved running and dancing," they said. "She was a born leader."
Catherine Hubbard, 6
The little girl with bright red hair will be remembered for her smile and her love of animals.
Catherine is survived by her older brother, her parents, grandparents, great-grandmother, uncles, aunts and nine cousins.
