Candy Arthurs died protecting her grandchildren.
"She always said she would die for them, and that's exactly what she did," Arthurs' daughter Amanda Gibson told WCMH.
According to police, a sex offender stabbed Arthurs in Columbus, Ohio, at the end of June.
Gibson said: "She's definitely a hero. It's hard because she lost her life, but she saved both of my kids' lives that night."
Arthurs has five grandchildren.

The 45-year-old died Wednesday at a local hospital after a month of being treated for her injuries.
Authorities say registered sex offender Kristopher Amos asked a group of children to help him find his drone. When Arthurs approached the 29-year-old, he reportedly stabbed her 7-year-old grandson in the shoulder. Police believe Amos then went after her.
The 7-year-old is doing well and is expected to fully recover at Nationwide Children's Hospital.
Amos has since been charged with one count of murder and two counts of assault with a bond set at $2.5 million.
Reports say neighbors in the area didn't know that Amos was a sex offender. In 2010, he was put on the register after he tried to get kids to shower with him at a YMCA.
Arthurs' family set up a GoFundMe page to help with medical costs and funeral arrangements. It has raised more than $6,800 as of Saturday morning.
