Graves was born in Tasmania, Australia, and worked as a farmer.
However, as this was an Irish peerage it did not entitle him to a seat in the House of Lords.
Lord Graves married Marjorie Ann, OAM (1992), on 13 March 1957.
He died on 6 December 2002, aged 76, leaving two sons (one deceased), two daughters and 10 grandchildren.
