Murder victim Jennifer Poole was remembered as having a "heart of gold" by her brother Jason during a service on Sunday.
The service was held in The Sensory Garden in Edenmore to remember those who have died from domestic violence and pray for survivors still living with it.
Jason Poole was one of the guest speakers at the event and urged anyone experiencing domestic violence to seek help.

He said: "Jennifer had a heart of gold. She was hard working, caring and loved her family and children very much.
"She was independent and ambitious, she loved her music and she loved to dance.
"She would always have a smile even though life, as we found out, was not great behind closed doors.
"Jennifer went from one violent relationship to another, as she thought this kind of violence was normal and acceptable.
"This kind of violent behaviour is not normal or acceptable, neither is the verbal, emotional, sexual or financial abuse that victims are going through and that survivors have went through.
"I ask people who feel like Jennifer and who feel like this is normal or if they can't get away, to please seek help and support.
"Jennifer didn't and she lied to us, her family, about what was going on and in the end, it was too late for her."
Ainie Grainger, one of the founders of Stop Domestic Abuse in Ireland, also spoke at the event and described the support victims can avail of.
"What we do is, if a victim comes to us and says they need help, we ask if there are kids involved.. have you gone to the courts, have you looked at legal aid," she said.
"And if they don't have a clue then we guide them on what they need, if it's a barring order, safety order, protection order, access, anything, we help as much as we can."
Lord Mayor of Dublin Alison Gilliland was in attendance too and said the stigma around domestic violence needs to end.
She said: "I think perhaps over the past year since Covid-19, we do know that the incidents of domestic violence really escalated and people have begun talking about it more.
"There is a stigma around domestic violence and I think that's no more than a stigma around mental health that we really have to get rid of."
Sunday's event was organised by Theresa Kelly with the help of Coolock garda station.
