Many people in Newry, and far beyond are suffering a huge loss.Canon Francis Brown"Any death in our community saddens us. We feel especially for the relatives and the friends," Canon Francis Brown told mourners gathered for the funeral service."Death is always a shock; even if we know that a person is not well. At a time such as this, we have many words and few words - many words to say what is unimportant and few words to say the real, caring things to each other."Dr Haughey, who was made a UUP peer in 2004 before switching to the Conservative Party, was one of Northern Ireland's richest men and founded the world-renowned Norbrook Laboratories.Canon Brown paid tribute to him as "a self-taught, hard-working, determined individual who had a thirst for knowledge" and who had made significant donations to charities and schools without recognition.He added: "In the late 1960s, Edward returned to Ireland and set up Norbrook Laboratories, bringing employment to many people in the city of Newry and the surrounding area."Edward started as a sole trader operating on a very small scale and grew the business to its present scale. As Chairman and Managing Director of Norbrook Laboratories Ltd. and Norbrook Holdings, he employed approximately 3,000 people globally, with 2,000 staff based in Newry City - many of them graduates and highly qualified PhD scientists."Dr Haughey is survived by his wife Mary, daughter Caroline and sons Edward and James.
