The bodies of 27-year-old Jolanta Lubiene and her eight-year-old daughter Enrika have been flown from Dublin to Frankfurt and will arrive in Lithuania tonight.
Their funerals will take place on Monday in their native village near the city of Telsiu.
Their bodies were discovered at their home in Killorglin, Co Kerry last month.
Lithuanian national Aurimas Andruska, 26, has been charged with their murders.
Ms Lubiene's husband Marius, her sister Kristina and other family members have left Co Kerry for the funeral.
