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.
"Her family prays that she, all the students of Sandy Hook Elementary, and all those affected by this brutal event find peace in their hearts," they wrote in her obituary.
In lieu of flowers, her family asked that people make donations to the Newtown Animal Center.
A Facebook page honoring Catherine spoke of how she is now an angel.
"Such a beautiful little soul," the post read, saying the family's loss is heaven's gain.
Chase Kowalski, 7
What Chase really wanted for Christmas was two front teeth.
"I saw him two days ago, and I asked him if he wanted to see Santa, and he told me that he wanted his teeth back, and it was really sweet," Chase's neighbor Keeley Baumann, 13, told the News-Times newspaper.
At 6, he completed his first triathlon, but that was just one of his pursuits. He loved baseball. He was in the Cub Scouts. He looked forward to the kids' workshop at the local Home Depot.
"We are thankful to the Lord for giving us seven years with our beautiful loving son. It is with heavy hearts that we return him," the family said in an obituary.
Jesse Lewis, 6
Jesse loved math, riding horses and playing at his mom's farm, his father told the New York Post.
"He was just a happy boy," Neil Heslin said. "Everybody knew Jesse."
He told the newspaper that his son was to make gingerbread houses at school Friday. Heslin was planning to help.
Instead, the last time he saw his son was when he dropped him off at school at 9 a.m.
"He was going to go places in life," Heslin told the Post.
Ana Marquez-Greene, 6
"One, two, three, ready and go," Ana counts down in a homemade video provided to CNN affiliate WTIC.
The girl in pigtails stands in front of a piano as her brother plays. Her voice is clear, bigger than her size. Ana smiles and waves.
Her father, Jimmy Greene, is a jazz musician. His representative released a statement on Ana's death, describing the little girl as "beautiful and vibrant."
"The family has requested privacy at this time of heartbreaking loss," it read. They "have asked us to relay their sincere gratitude for the outpouring of support and sympathy locally, nationally and internationally."
James Mattioli, 6
As he was quick to remind everyone, James was 6 and ¾.
