Michael, I have acquired Sarah's death cert and it is in the name of Sarah Bunting and suggests to me unless there is some code involved, that this was natural causes,  viz.  "Perforation of bowel 29 hours ". Registered in Oldham sub district of Royton, Lancs. 2nd June 1880. Sarah's granddaughter, my Aunt, still believes in the suicide story but we have no way of proving either way now. I have found no newspaper reports, although my Aunt has now found a surviving first cousin thanks to Mary and to genes reunited site members and I hope that I may find more from the cousin soon. Jim
