My GGGF Duncan McCallum (1814 - Apr.11, 1892[Taynuilt]), was the son of an Archibald McCallum & Sarah Buchanan, they were reportedly from somewhere in the Kilmore-Kilbride/Black Lochs region to the south of Oban. He was married to Jane McInnes (1814 - Mar.26,1898[Athol Villa, Oban]), the daughter of John McInnes and Margaret Campbell. My problem is that I cannot locate any definite origin places by name for either this A. McCallum or this John McInnes. Any assistance from those familiar with this area of Argyll would be a God send to my research
