"incidentals such as burial sites are inconsequential"
.,,.
Not always so, Susan. In that very ballad you quote, as well as others like 'Little·Musgrave/Matty·Groves', burial sites are in many versions indicative of social precedence; with instructions for burial in one grave combined with such an injunction as to bury one of them in a superior position "for she came of the nobler kin".
