Two remorseless killers will serve more time in prison after being found guilty of murder for a second time.
But the family of the woman and her four children who died say no sentence will ever be enough.
Zak Bolland, 26, and David Worrall, 29, have had around three years added to their life sentences after being convicted of Michelle Pearson's murder in a petrol bomb attack at her Salford home.
Four of Michelle's children also died in the blaze at their Walkden house - 15-year-old Demi; eight-year-old Brandon; seven-year-old Lacie; and Lia, three.
Bolland had been involved in a tit-for-tat feud with one of their siblings, Kyle Pearson.
Michelle's mother said the deaths had 'torn apart' and 'destroyed' her 'utterly heartbroken' family.
Bolland and Worrall were found guilty of the murders of the children at a trial in 2018, and received life sentences and were ordered to serve a minimum of 40 and 37 years respectively.
After being found guilty of Michelle's murder at a second trial, the pair were sentenced on Wednesday.
Their barristers argued they should not have their minimum terms increased.
But the judge, Mrs Justice McGowan, said the previous sentences did not reflect the mental and physical suffering Michelle endured in hospital, where she remained from the fire in December 2017 until her death about 20 months later.
"The loss of a life must be marked," the judge said.
She again handed them life sentences, to serve a minimum of 40 and 37 years respectively.
The judge said both sentences would start from today (Wednesday), meaning the period from when they were previously sentenced, in May 2018, until now, would not count towards their minimum terms.
Courtney Brierley, 23, Bolland's former girlfriend, was found guilty of manslaughter at the first trial after she 'encouraged and assisted' the pair.
She then admitted the same offence before the second trial.
Brierley was originally sentenced to 21 years, of which she would have to serve half.
She was today sentenced to 12 years. Under new laws passed since the first sentencing, she now has to serve two-thirds of that sentence.
It is thought that she will have to serve about eight months additional time in custody.
Members of the Pearson family were present at Manchester Crown Court for the case.
Outside court, a statement was given on behalf of Sandra Lever, Michelle's mother and grandmother to the children.
Reading out the statement, Detective Chief Inspector Cheryl Chatterton held a piece of paper featuring pictures of the youngsters.
In the statement, Ms Lever said: "We are still trying to come to terms with how cruelly they were taken away from us.
"A whole family has been torn apart and destroyed in one night.
"Nothing will ever bring them back, and my family will never be the same again.
"Losing Michelle and the children is still very raw, and we are still struggling to come to terms with losing them, especially the way in which they died.
"It is hard enough to lose one person that you loved, through being deliberately and cruelly taken away from you.
"But to lose five is unbearable.
"The sentences that have been given will never be enough.
"No amount of time will ever be enough.
"We have not just lost four beautiful grandchildren, but my amazing daughter.
"Michelle and the children filled a massive place in all our hearts, and our family will never be the same again.
"We are all utterly heartbroken, and will forever be.
"Michelle had so much more to give this world, and the children had a full life ahead of them.
"We were expecting the defendants to all plead guilty to the murder of Michelle, having already been found guilty of the murders of the children.
"The family should not have had to relive the devastating details from that fire all over again.
"Not once have they shown any remorse, or said sorry for the murders of my daughter and grandchildren.
"We believe that if Michelle didn't die from her injuries sustained from the fire, we believe that she would have died from a broken heart.
"Michelle and her children are now reunited in heaven, and there is not a day that goes by when we don't think of them."
DCI Chatterton said: "This was a heartbreaking case and I'm glad that the trio have now faced justice for the devastating death of Michelle too - 20 months on.
"The bravery shown by the family and those affected has been outstanding - they have shown so much strength throughout both of our investigations.
"Bolland and Worrall planned the attack and travelled to the address with Brierley where the two men threw their handmade petrol bombs inside.
"That night in 2017 rocked the community and has turned the family's life upside down. All of our thoughts are with the family who have been through such a difficult time and have had to sit through two trials and listen to details on what was a horrific and planned attack.
"Nothing can bring Michelle and the children back, but I hope they can now be given time to grieve and come to terms with what has happened."
