POSTHUMOUS

Born after the death of one's father.

Example: "Posthumous orphans never even knew their fathers."

After the death of someone

Example: "Usage note: posthumous awards are made when the intended recipient dies as a result of the action which merits the award. even a short time lag between the action and the decision may cause the award to be conferred after death or there may be a longer delay such as when a review board decides to confer an award decades after a war has ended but such awards while they may be post mortem (literally, "after death") are not posthumous awards."

Taking place after one's own death

Example: "Artists obscure during their life often receive posthumous recognition, too late for them to enjoy."

In reference to a work, published after the author's death.

Example: "His memoirs were his posthumous revenge on enemies he dared not take on alive."
