Of the 38 victims of the attack on a beach near Sousse on June 26, 2015, 30 were British and an inquest has already been held this year into the tragic event.
Now, lawyers Irwin Mitchell, which are representing the families of 22 of those killed in the attack have spoken of how they are trying to take some good from the event.
Suzy Richards, from Wednesbury in the Midlands, lost her son Joel, father Pat and brother Ade in the attack.
Since the tragedy, she and her other son Owen have founded the charity Smile for Joel, which seeks to help families traumatised by homicide.
Meanwhile, Cheryl Stollery, whose husband John was killed, is using her job as safeguarding children in education officer for Nottinghamshire County Council to raise awareness of the threat of terror, hate and knife crime, bringing together agencies to share information.
Kylie Hutchison, a specialist international personal injury lawyer at Irwin Mitchell, said: “Our clients have shown tremendous courage over the past two years as they have sought to find out exactly what happened on that fateful day and whether anything more could have been done to prevent the attack, or limit its impact.
“The seven-week inquest was particularly difficult, sitting through hours of sensitive and often shocking evidence.
“They now await the coroner’s report and hope that recommendations will be made to reduce the risk of similar incidents in the future.”
Since the inquest earlier this year, the man in charge Judge Loraine-Smith has taken further submissions from Irwin Mitchell and Tui.
He is expected to publish his report into possible action to learn lessons from the tragedy in the coming months.
A criminal investigation in Tunisia is also ongoing with a hearing scheduled for October.
