(CNN) -- The Tennessee Supreme Court on Wednesday refused to modify or overturn a lower court's ruling allowing Mary Winkler, convicted of killing her minister husband, visitation rights with the couple's three daughters. 

Holding baby Brianna, Mary Winkler stands next to Matthew. In the foreground are Mary Alice and Patricia. 

Charles and Diane Winkler, parents of slain minister Matthew Winkler, had asked the court to intervene and either revoke Mary Winkler's visitation rights or allow them to proceed only under supervision of a counselor. 

The children -- Patricia, Mary Alice and Brianna -- have been living with their grandparents since their mother was arrested last year. 

Winkler has not seen the children in 15 months, said Kay Farese Turner, her attorney. She said her client was "absolutely elated about the news and believes this will be her best Christmas ever." 

Turner said she believes the visit may come before Christmas. 

A jury convicted Winkler earlier this year of voluntary manslaughter in the shotgun death of Matthew Winkler -- not the first-degree murder conviction prosecutors had wanted. She said the slaying came after years of abuse, including physical violence and being forced to dress "slutty" for undesirable sex acts. 

Winkler received a three-year sentence, but a judge required her to serve only 210 days, gave her credit for the five months she had already served and allowed her to serve the remaining 60 days in a mental health facility. She was released in August. 

At the time of their father's death in March 2006, Patricia was 8, Mary Alice was 6 and Brianna was 1.
