There are 2 George Steeps living in Huron County but neither of them had a wife named Emily.
What did your grandfather change his name to? What name was he married under? What was his wife's name? Was he in WW1? All this information can be checked.
Where did he go when he left home? There are quite a few George Miller's on the 1911 census but if you know where he was living, you might find him.
He kept in touch with someone if he knew one of his parents had died.
George Miller, b 1850, died 25 April 1920 so this could have been the funeral that he attended.
