"She was a member of our church and of our craft group. I will miss her great disposition, her laugh, and smile. She was always a helper, such a sweetheart. Our prayers go out to her children and grandchildren," Julie Crane posted on her Facebook wall.
Crane told ABC News that she attended Norminster Presbyterian Church with Schneck and was on the crafts committee with her. Members of the church remembered her at services today.
"There were a lot of tears today," Crane said. "We're going to miss Phyllis a great deal."
Schneck was a widow who spent part of the year in Tucson and her summers in her native New Jersey. She was a mother of three and a grandmother, Crane said.
Crane had received a robo-call from Giffords and went to the political gathering to see Giffords speak, Crane said.
"She was very interested in what our government is doing," Crane said.
The grandmother was known for her ability to bake sweets like almond cookies and brownies with mint chips in them. She also was a talented seamstress, sewing beautiful quilts, Crane said.
Also lost in the shooting was U.S. District Court Judge John Roll. Roll, 63, had served on the U.S. District Court for the District of Arizona since 1991.
"He was a good judge," said retired Chief Judge Thomas Zlaket, who sat on the bench with Roll. "But first and foremost he was a good human being."
Tucson Bishop Gerald F. Kicanas recalled that Roll often attended early morning mass before work.
"Judge Roll was a person of great faith and great integrity," Kicanas said in a statement. "He lived his faith as a servant of our nation for the cause of justice."
Roll leaves behind a wife, three sons and five grandchildren.
Gabriel Zimmerman, a staffer for Giffords, also died. Zimmerman, 30, was the director of community outreach for the congresswoman.
He was a former social worker and leaves behind a fiancee.
