I also am descended from the Urney Loughlins (I beleive I link in with Mervyn's ancestors). Probably coincidently I know of another Loughlin - Bogle marriage. In 1920 my grandmother's brother Robert Loughlin married a Frances Bogle. I believe the marriage took place in Johnstone, Scotland however there is no reason to believe that Frances was not also from Tyrone.
