Riddle, Oliver born 1815 County Tyrone, moved to Canada about 1932

Looking for parents or siblings of Oliver Riddle born 1815 in County Tyrone.  I only know this because is says he is a native of County Tyrone on his tombstone.  He moved to Canada around 1832 and married Elizabeth Boucher.  His children included:  James Samuel and Wm Oliver, John Henry and several daughters.  This family has a habit of calling their children by their middle names so I am not sure Oliver is his real first name or not.  His son was Wm Oliver but always known as Oliver so I'm not sure about the original Oliver.  He always lists Church of England.  Thanks for any help you can give me
