Pontiac Daily Leader, Monday, Dec 7, 1903
Irving (Ervan) L. Denning, a well known brick mason of this city, died in Chicago at the Presbyterian hospital at two o'clock this morning, death being due to an abscess of the liver.
Mr. Denning was taken to Chicago some time ago where he underwent an operation for his trouble, and had been gradually improving. Sunday his wife visited him and he appeared to be excellent sprits, chatting and laughing with her. She left there last night, returning to the city and was notified of his death this morning.
Mr. Denning was quite well known in this city and was an expert at his trade. For several years he was an instructor in bricklaying at the Reformatory. He leaves a wife and three children. No definite arrangements have been made regarding the funeral but the remains will be brought to this city this evening.
