Resources in Kilmartin Argyll

Hello - I will be in Kilmartin in June. So far I have used Elgin County records, Scotland's Peoples, Ancestry.com and our family Bible for my research.My last record of our McCallum family is at 10 Slockavullin in 1851.  Can anyone recommend local places/persons in the Kilmartin/Kilmichael area that hold census/family records ?Many thanks,Laura
