The dead woman’s children – Affira (11) and her six-year-old brother Fazan – were found face down in a bedroom of the family home on Llewellyn Court and gardaí believe they were strangled.
The mother of two, who was from India and had been living in Ireland for many years, was the victim of an alleged assault earlier this year.
A male suspect had been identified for that attack in May, which left her very seriously injured and resulted in her losing consciousness.
Seema Banu had also been in contact with the authorities amid concern for the family’s welfare in the aftermath of that attack.
Gardaí were alerted by neighbours late on Wednesday morning about their concerns for the family and officers arrived on the scene just after midday.
It is understood the victims had been dead for some time and a tap that had been left running had flooded the property.
The dead woman’s husband, and the father of the two deceased children, was later contacted by gardaí.
He and a legal representative have been speaking to the investigating team.
No arrests in the case had been made on Wednesday night.
Garda Headquarters on Wednesday asked members of the public to desist from posting speculation about the case on social media.
On Wednesday night on the main green area on the estate, off Llewellyn Lawn, about 200 local people came out to remember the dead and left candles under the largest tree in the park.
