PRIOR TO 1825, COL. THOMAS AMBLER, NEPHEW OF JOHN MARSHALL, MOVED WITH HIS WIFE TO MORVEN WHICH WAS THEN A ONE-STORY LOG HOUSE. WINGS WERE ADDED – GIVING THE OLD HOME THE SHAPE OF A MALTESE CROSS WITH COLUMNED PORCHES AT THE THREE FRONT ENTRANCES. THE PRESENT OWNERS OF THE HOUSE ARE DIRECT DESCENDENTS OF JOHN MARSHALL
