Friends of Anne Colomines have launched a fundraising drive to raise money to support her family.
Ms Colomines (37), who was originally from France, was found dead in her home on Gardiner Street, in north inner city Dublin, on October 24.
The financial executive had suffered from apparent stab wounds.
Ms Colomines' husband, Brazilian national Renato Gehlen (35), is expected to appear in court this morning charged in connection with the case.
Ms Colomines was from Charente-Maritime, on the south-west coast of France, and it is understood she moved to Dublin in 2013.
She had been working with PayPal as a financial executive at its Dublin base at the time of her death.
In a page set up on the crowdfunding website Leetchi, in both English and French, her friends said they wanted to honour Ms Colomines's memory.
"With the sudden death of Anne, her family face a cataclysm, but also must honour her memory and ensure that justice will be done," the message said.
"This involves a solicitor in Ireland and other expenses related to a future procedure that may be long and costly.
"Her family needs our support for this, friends of Anne of Charente-Maritime, Dublin or elsewhere."
While the site does not give a figure for the total amount raised, there have been 79 contributions from donors so far.
Following her death, friends and colleagues paid tribute to Ms Colomines.
"She was a very kind person," said one friend, who asked not to be identified.
"At work, she was very hardworking and always happy to help others.
"I didn't know anyone who disliked her.
"Anne spent a lot of time volunteering with homeless cats. She loved her cat, Kitty, with all her heart.
"She was quiet and worked a lot but enjoyed going out for dinner with friends. Her friends and her family made her really happy.
"Anne was such a kind, fun-loving friend, who wore her heart on her sleeve. She'll be missed so much."
Ms Colomines was an animal lover and on several occasions she referenced the Phibsboro Cat Rescue charity on her social media account.
The charity confirmed she had been in touch with it in the past with a view to volunteering and carrying out fundraising activities.
"She was a really kind lady. We are very sad to hear what has happened," said a spokeswoman for the charity.
