A video spreading across the Internet shows a confident Ana hitting every note as she sings "Come, Thou Almighty King." She flashes a big grin and waves to the camera when she's done.
Jorge Marquez confirmed the girl's father is saxophonist Jimmy Greene, who wrote on Facebook that he was trying to "work through this nightmare."
"As much as she's needed here and missed by her mother, brother and me, Ana beat us all to paradise," he wrote. "I love you sweetie girl."
JAMES MATTIOLI, 6
The upstate New York town of Sherrill is thinking of Cindy Mattioli, who grew up there and lost her son James in the school shooting in Connecticut.
"It's a terrible tragedy, and we're a tight community," Mayor William Vineall told the Utica Observer-Dispatch. "Everybody will be there for them, and our thoughts and prayers are there for them."
James' grandparents, Jack and Kathy Radley, still live in the city, the newspaper reported.
ANNE MARIE MURPHY, 52, teacher
A happy soul. A good mother, wife and daughter. Artistic, fun-loving, witty and hardworking.
Remembering their daughter, Anne Marie Murphy, her parents had no shortage of adjectives to offer Newsday. When news of the shooting broke, Hugh and Alice McGowan waited for word of their daughter as hours ticked by. And then it came.
Authorities told the couple their daughter was a hero who helped shield some of her students from the rain of bullets. As the grim news arrived, the victim's mother reached for her rosary.
"You don't expect your daughter to be murdered," her father told the newspaper. "It happens on TV. It happens elsewhere."
EMILIE PARKER, 6
Quick to cheer up those in need of a smile, Emilie Parker never missed a chance to draw a picture or make a card.
Her father, Robbie Parker, fought back tears as he described the beautiful, blond, always-smiling girl who loved to try new things, except foods.
Parker, one of the first parents to publicly talk about his loss, expressed no animosity for the gunman, even as he struggled to explain the death to his other two children, ages 3 and 4. He's sustained by the fact that the world is better for having had Emilie in it.
"I'm so blessed to be her dad," he said.
NOAH POZNER, 6
Noah was "smart as a whip," gentle but with a rambunctious streak, said his uncle, Alexis Haller of Woodinville, Wash. Noah's twin sister Arielle, assigned to a different classroom, survived the shooting. He called her his best friend, and with their 8-year-old sister, Sophia, they were inseparable.
"They were always playing together, they loved to do things together," Haller said. When his mother, a nurse, would tell him she loved him, he would answer, "Not as much as I love you, Mom."
Haller said Noah loved to read and liked to figure out how things worked mechanically. For his birthday two weeks ago, he got a new Wii.
"He was just a really lively, smart kid," Haller said. "He would have become a great man, I think. He would have grown up to be a great dad."
LAUREN GABRIELLE ROUSSEAU, 30, teacher
Lauren Rousseau had spent years working as a substitute teacher and doing other jobs. So she was thrilled when she finally realized her goal this fall to become a full-time teacher at Sandy Hook.
Her mother, Teresa Rousseau, a copy editor at the Danbury News-Times, released a statement Saturday that said state police told them just after midnight that she was among the victims.
"Lauren wanted to be a teacher from before she even went to kindergarten," she said. "We will miss her terribly and will take comfort knowing that she had achieved that dream."
Her mother said she was thrilled to get the job.
"It was the best year of her life," she told the newspaper.
Rousseau has been called gentle, spirited and active. She had planned to see "The Hobbit" with her boyfriend Friday and had baked cupcakes for a party they were to attend afterward. She was born in Danbury, and attended Danbury High, college at the University of Connecticut and graduate school at the University of Bridgeport.
She was a lover of music, dance and theater.
"I'm used to having people die who are older," her mother said, "not the person whose room is up over the kitchen."
MARY SHERLACH, 56, school psychologist
When the shots rang out, Mary Sherlach threw herself into the danger.
Janet Robinson, the superintendent of Newtown Public Schools, said Sherlach and the school's principal ran toward the shooter. They lost their own lives, rushing toward him.
Even as Sherlach neared retirement, her job at Sandy Hook was one she loved. Those who knew her called her a wonderful neighbor, a beautiful person, a dedicated educator.
Her son-in-law, Eric Schwartz, told the South Jersey Times that Sherlach rooted on the Miami Dolphins, enjoyed visiting the Finger Lakes, relished helping children overcome their problems. She had planned to leave work early on Friday, he said, but never had the chance. In a news conference Saturday, he told reporters the loss was devastating, but that Sherlach was doing what she loved.
"Mary felt like she was doing God's work," he said, "working with the children."
VICTORIA SOTO, 27, teacher
She beams in snapshots. Her enthusiasm and cheer was evident. She was doing, those who knew her say, what she loved.
And now, Victoria Soto is being called a hero.
Though details of the 27-year-old teacher's death remained fuzzy, her name has been invoked again and again as a portrait of selflessness and humanity among unfathomable evil. Those who knew her said they weren't surprised by reports she shielded her first-graders from danger.
"She put those children first. That's all she ever talked about," said a friend, Andrea Crowell. "She wanted to do her best for them, to teach them something new every day."
Photos of Soto show her always with a wide smile, in pictures of her at her college graduation and in mundane daily life. She looks so young, barely an adult herself. Her goal was simply to be a teacher.
"You have a teacher who cared more about her students than herself," said Mayor John Harkins of Stratford, the town Soto hailed from and where more than 300 people gathered for a memorial service Saturday night. "That speaks volumes to her character, and her commitment and dedication."
