The body of Irishman Andrew Grene has been found in the wreckage of the UN building in Haiti's capital Port-au-Prince.

Grene was working in Haiti as a special assistant to Hedi Annabi, the head of the UN mission who was killed in the earthquake.

Grene, 44, who held joint Irish and US citizenship, was married to County Down native Jennifer. They have three teenage children.

Grene was the twin brother of Greg Grene, the founder of the well-known Celtic rock group The Prodigals.
 
His friend, and Irish Voice rock columnist Mike Farragher today paid tribue to Grene on his Facebook page.

"RIP to Andrew Grene...father of 3, husband, son, twin brother to my friend Greg. Andrew died in the UN building collapse, trying to make life better for Haitians. My thoughts and prayers go out to the Grene family and all those who have lost loved ones in Haiti."

Grene was born in Chicago but grew up living between County Cavan and the U.S. as a child. He lived on a small farm near Belturbet in County Cavan.
 
Grene attended the University of Chicago and then went to Trinity College Dublin. He then attended the Medill School of Journalism and won a national journalist award for investigative journalism on patronage in the Illinois court system.
 
He worked as a speechwriter for the former UN secretary general Boutros Boutros Ghali and then moved into peacekeeping strategy.
 
Grene's father was born in Ireland and became a professor at the University of Chicago. His half brother Nicholas Grene is currently a professor of English at Trinity College Dublin.
 
His mother Ethel is an emergency room doctor and is American born and bred.
