Arrived in South Australia on 'Sir Charles Forbes'.
A 1907 newspaper obituary of Christina McLean (nee Black) mentions that she migrated with her uncle 'Mr J McDugall of Saddleworth'. But the obituary listed the wrong uncle. James McDougal (1810-1856), who was mentioned in this obituary, was a younger brother of Archibald. He lived in the area around Saddleworth in South Australia and he married Jane/Jean Paul in 1838 in Glasgow. He arrived in South Australia in 1839 on the 'Sir Charles Forbes'.
