The couple were on holiday in Sousse when they were shot by the gunman.
The terror attack claimed 38 lives; three of them Irish. Lorna Carty, an Irish mother of two from Robinstown, Co Meath was also killed in the attack.
Meanwhile the bodies of nine victims of the massacre have been returned to the UK, as the final British death toll was confirmed at 30.
The coffins carrying the remains of Lisa and William Graham, Philip Heathcote, Trudy Jones, Ann and James McQuire, Janet and John Stocker, and David Thompson were loaded into hearses in a sombre ceremony at RAF Brize Norton in Oxfordshire.
Military personnel unloaded the coffins, which were topped with floral arrangements, and slowly carried them from the RAF C-17 transport plane used to bring them back from Tunisia into the waiting hearses.
The task, performed by members of the RAF Regiment's Queen's Colour Squadron, was witnessed by relatives of the dead who were present at the airbase.
Eight Britons killed in the terror attack were brought back to British soil yesterday, and further flights are expected tomorrow and on Saturday.
British nationals made up the majority of the 38 killed by gunman Seifeddine Rezgui when he opened fire on holidaymakers on a beach in the resort of Sousse on Friday - along with three Irish nationals, two Germans, one Belgian, one Portuguese and one Russian.
Foreign Secretary Philip Hammond said: "We now have all 30 British victims positively identified and we can say with a high degree of confidence that is now the final death toll of British nationals killed in this incident."
Tributes have been paid to the UK and Irish citizens who were gunned down at the Sousse beach resort while on holiday in Tunisia.
