James MacQuillin/en Dublin 1765
Looking for a James MacQuillin/en born in Dublin in 1765.  The family may have moved to England when he was small as he ends up in the late 1700s as an apprentice to a taylor in Beauford Buildings, The Strand London.  He returns to Ireland for 2 and half years to find a wife before returning to London to finish his apprenticeship.  He marries an Elizabeth (who could possibly be Catholic - James is Church of Ireland).  In 1800 the family move to Colchester in Essex (England).  Any help would be gratefully received as I have no idea where to start!
