The mother-of-10, a Protestant, was originally from east Belfast and converted to Catholicism after marrying Arthur McConville.
After being intimidated out of east Belfast, the family moved to west Belfast and set up home in the Divis flats on the Falls Road.
Not long after the move in 1971, Arthur McConville died from cancer.
She was taken from her home by the IRA in December 1972.
There had been speculation that she was taken after being seen by neighbours helping an injured British soldier.
Others claimed she was an informer, but this was dismissed after an official investigation by the Northern Ireland Police Ombudsman.
Those known as the Disappeared had been abducted, murdered and secretly buried by republicans.
The IRA admitted in 1999 that it murdered nine of the Disappeared - including Jean McConville - and buried them at secret locations.
It was several years later, in 2003, that her body was finally found on Shelling Hill Beach in County Louth in the Republic of Ireland.
Irish police confirmed that she had died from a bullet wound to the head.
In the days that followed, the IRA issued a statement apologising for the grief it had caused the families of the Disappeared and that their suffering had continued for so long.
