Do we know whether or not Ireland would have been granted Home Rule? Yes of course we do, it was one of the items of business to be addressed put at the top of the Westminster Governments order of business after the end of the Great War - don't take my word for it consult Hansard and any history book covering the topic at the time.

Carroll should read up on Parliamentary procedure the House of Lords having objected the Irish Home Rule bill for the Third time in 1914 means that as far as the House of Lords went that was the end of their objections and the Bill would receive Royal Assent irrespective of their objections and that is what DID IN FACT HAPPEN.
