Context paragraphs:

She headed the UDA's women's department and ran the public relations and administration section at the organisation's headquarters in Gawn Street, off the Newtownards Road.  An outspoken critic of strip searching female prisoners, she was a founder and activist for "Justice For Lifers", an organisation which advocated prison reform in Northern Ireland.

Billy Hull: William "Billy" Hull (born 1912) was a loyalist activist in Northern Ireland.  Hull was a leading figure in political, paramilitary and trade union circles during the early years of the Troubles.  He is most remembered for being the leader of the Loyalist Association of Workers, a loyalist trade union-styled movement that briefly enjoyed a mass membership before fading.

Red Hand Defenders: The Red Hand Defenders (RHD) is an Ulster loyalist paramilitary group in Northern Ireland.  It was formed in 1998 by loyalists who opposed the Belfast Agreement and the loyalist ceasefires. Its members were drawn mostly from the Ulster Defence Association (UDA) and Loyalist Volunteer Force (LVF).  The name had first been used by Red Hand Commandos dissident Frankie Curry in 1996 and he was the leading figure in what was a somewhat unstructured organization until he was killed in 1999.  It is named after the Red Hand of Ulster.

Loyalist Volunteer Force: The Loyalist Volunteer Force (LVF) is a small Ulster loyalist paramilitary group in Northern Ireland.  It was formed by Billy Wright in 1996 when he and his unit split from the Ulster Volunteer Force (UVF) after breaking its ceasefire.  They had belonged to the UVF's Mid-Ulster Brigade and Wright had been the brigade's commander.  In a two-year period from August 1996, the LVF waged a paramilitary campaign with the stated goal of combatting Irish republicanism.  During this time it killed at least 14 people in gun and bomb attacks.  Almost all of its victims were Catholic civilians who were killed at random.  The LVF called off its campaign in August 1998 and decommissioned some of its weapons, but in the early 2000s a loyalist feud led to a number of killings.  Since then, the LVF has been largely inactive, but its members are believed to have been involved in rioting and organized crime.  In 2015, the security forces stated that the LVF "exists only as a criminal group" in Mid-Ulster and Antrim.

Andrew Robb and David McIlwaine killings: The Tandragee killings took place in the early hours of Saturday 19 February 2000 on an isolated country road outside Tandragee, County Armagh, Northern Ireland.  Two young Protestant men, Andrew Robb and David McIlwaine, were beaten and repeatedly stabbed to death in what was part of a Loyalist feud between the loyalist Ulster Volunteer Force (UVF) and their rivals, the breakaway Loyalist Volunteer Force (LVF).  The men were not members of any loyalist paramilitary organisation.  It later emerged in court hearings that Robb had made disparaging remarks about the killing of UVF Mid-Ulster Brigade leader Richard Jameson by an LVF gunman the previous month.  This had angered the killers, themselves members of the Mid-Ulster UVF, and in retaliation they had lured the two men to the remote lane on the outskirts of town, where they killed and mutilated them.

John White (loyalist): John White (born 1950) is a former leading loyalist in Northern Ireland.  He was sometimes known by the nickname 'Coco'.  White was a leading figure in the loyalist paramilitary group, the Ulster Defence Association (UDA) and, following a prison sentence for murder, entered politics as a central figure in the Ulster Democratic Party (UDP).
