what did the old bachelor want to do over a hundred years later to appease matthew maule and why doesn't it happen

The old bachelor believed that Matthew Maule had been foully wronged out of his homestead and life. This bachelor wished to make restitution to Maule's posterity, and might have even given up the House of the Seven Gables to the representative of Matthew Maule. Upon his death, the house passed to his nephew, the cousin of the man convicted of murder.
