From a typescript of the obituary, included in the Gratton family files and probably done by Wilfred Harrison.
Derbyshire Courier, November 13, 1886
An old Dronfield Liberal has just gone to that place where oppositions cease from troubling, and politicians are at rest. Jame Grattan, locally known as the Mayor of Dronfield, probably from the interest he took in the sittings of the local magistrates which he attended with greater regularity than any of the J.P's upon the Bench, died on Friday. Many years ago he was landlord of the Green Dragon Inn in that town. He was an enthusiastic Liberal and a firm believer in Mr. Gladstone and all his works, and was a familiar and prominent figure in all the demonstrations of the party which have taken place any time during the past half century. His advocacy of Liberalism was chiefly confined to narrating the stirring events which occurred during the first elections in the Division, and he was never so happy as when fighting his battle o'er again, in relating his exploits in connection with the agitation for the repeal of the Corn Laws. He took a gossiping interest in all local affairs, and his constant inquiry was if there was anything going off. At last he has gone off at the advanced age of 76.
James was buried on the 8th, so maybe the obituary meant he died on Friday the 5th, not the 12th.
