One of the 20 children who died in a shooting massacre at a Connecticut elementary school on Friday had recently moved to the U.S. state from Winnipeg, according to reports.

Jimmy Greene moved his family — including two school-age children, Isaiah and Ana Marquez Greene — from Winnipeg to Newtown, Conn., in July, according to family and friends in the Manitoba capital.

A number of local media reports have said Ana died in Friday's shooting, but the family has not confirmed this. One report said the information is based on an internal note sent by administration at Linden Christian School in Winnipeg, where the girl used to be a student.

Reached by phone on Friday, Greene's family told CBC News that one of their children, a boy, was fine. However, they would not confirm the status of the girl.

Whyte Ridge Baptist Church, a Winnipeg church that the family used to attend, held a vigil to honour Ana's life on Friday evening.

Terry Janke, the church's senior pastor, told CBC News that Greene confirmed Ana's death to a congregation member.

"Through these times it rocks anybody's world, losing a child, and so we're holding ourselves up in grief but holding them up that their faith be unshakable," Janke said.

Greene is a U.S. jazz musician who was a faculty member at the University of Manitoba's school of music for three years before his family moved to Newtown.

Winnipeg musician Steve Kirby, who is close friends with Greene's family, described the children as "really bright" and talented.

"Really talented, beautiful children. Picture-book children, and obedient and spiritual — you know, the kind of kids you want moving in next door," he said.

Janke said many of the children at the Whyte Ridge church quickly became friends with Isaiah and Ana, and some continued their friendships as penpals after the family moved to Newtown.

"Ana was just a sweet little girl," he said. "I mean, she just had a big smile on her face."
