Hi Pettsy, This probably won't help you much,
I notice from the other posting that Monica found Catherine McColl McAuley for you in 1841 in Drymen so I won't post that but just to let you know, I can't find anybody called William or Mary McColl on the 1841 old enough to have been Catherine's parents ...
I did find some McColl families living in Killearn (after saying I'd not come across that name in Killearn, turns out they lived in shouting distance of my 3G's who also lived in Village
)
Living in Village, Killearn,
James McColl, aged 36, Shepherd, born in Scotland
Elizabeth McColl aged 35, born in Stirlingshire
John McColl aged 9, born in Stirlingshire
Janet McColl aged 7, born in Stirlingshire
James McColl aged 5, born in Stirlingshire
Mary McColl aged 2, born in Stirlingshire
Also Village, another family,
Malcolm McColl aged 40, labourer, born in Scotland
Jean McColl aged 30, born in Stirlingshire
John McColl aged 3, born in Stirlingshire
James McColl aged 1, born in Stirlingshire
Lachlan McColl aged 30, male servant, born in Scotland, living at Anchinedham Lodge (think this is a mistranscription), Killearn
Jessie McColl aged 20, female servant, born in Stirlingshire, living at Ballikinrain, Killearn
I am wondering if they may be connected to yours? Also notice that the elder McColls were not born in Stirlingshire, McColl seems to be an awfully popular name in Argyllshire, might be worth a look there?
regards,
Lindsay
