Hi Sancti,
No the Census record is a transcript from Ancestry. I know at times the transcripts can be a bit dodgy, but this looks to be well done with none of the usual misspellings. Having spent a fortune on documents, I don't see that purchasing this one will make much difference. It would have been down to James Thomson, the head of the household, to complete the census form and whether Marion told him a porkie or not it is likely that this was her occupation recorded. The mystery is; why can I not find William or his Son-in-law Scott Clarkson + family in the 1871 census? I know it is a difficult one Santi, I have been searching on and off for weeks, but I thought perhaps a fresh mind might turn up something simple.
My thinking was; If William and the family were still at Linnbank Cottages in Nemphlar at the time of the 1861 census (census below) and there seems to be no record of the cottages in the 1871 census, then the family must have moved, but where to? Well, the 1871 census for Marion records her still living somewhere in Nemphlar. And further to that her death certificate states that she died in Nemphlar - 1875. I am assuming then, that their home was somwhere in Nemphlar at the time of the 1871 census. I did find one entry for a William Jacktar, purchased it, but when I examined it, it was actually for a William Lochart - bummer! So there you have it Sancti, they must be somewhere, but where?
