Juli, My family tree is riddled with the names John & Duncan. I had some difficulty researching our family tree while in Edinburgh a few years ago. The family did originate in Argyll. I did not come across any McNicols although I found marriage certificates naming Kilchrenan, I will be researching further. I did come across a gravestone in a churchyard at Inverary (Nr.Oban)which included a Mary McC died 1891. My first wife was Sarah Anderson from Edinburgh. A Sarah is also listed on the same gravestone. Sarah McCorquodale is also the sister of the late Princess Diana. Same names are always cropping up.
