The sisters and fiancée of murdered Belfast man Robert McCartney will today be awarded a prestigious bravery prize in Germany.
The women will be presented with the annual Die Qudriga Award (courage, vision and responsibility) in Berlin.
They came to prominence after the 33-year-old father-of-two was stabbed to death outside a Belfast bar in January.
Despite being subjected to a campaign of intimidation, they claimed the killer was a member of the IRA and was being shielded by the paramilitary group.
The judges praised the women's courage and dignity in the face of repeated threats.
Their campaign for justice took them to the White House for a meeting with President Bush in March. The McCartney sisters and Robert's partner, Bridgeen Hagans, have also travelled to London, Brussels and Dublin to raise the profile of their case.
One man has been charged with Mr McCartney's murder and is expected to stand trial next year.
A second is accused of attempting to murder the friend who was with him on the night he died outside Magennis' Bar in Belfast city centre.
The sisters and Ms Hagens will this week also be named among Timemagazine's European Heroes for 2005. The US news weekly recognises the women alongside Live8 organiser Sir Bob Geldof and Arsenal striker and anti-racism campaigner Thierry Henry.
