James McDonald faces two charges of attempting to murder Susan McDonald and Helen Seymour in Kirton, near Boston, on May 18.
McDonald, wearing a grey jumper, spoke only to confirm his name and did not enter a plea when he appeared at Lincoln Crown Court this morning.
He also faces a third allegation that he was in possession of a bladed article, namely a kitchen knife, on the same occasion in Kirton.
Judge John Pini QC adjourned the case for a date to be fixed.
McDonald, now of Arnold Lodge, Cordelia Close, Leicester, will next appear for a plea and case management hearing.
