Hi Ostler,
Sorry I didn't spot this post earlier. I am also related to the Sutherland family that you are searching for
My gggg grandmother Elizabeth Sutherland was Janet Sutherland's sister. Do you descend from Janet? She has another sister and a brother as far as I know, Jane Sutherland who married Thomas Rutherford and John Sutherland who remained unmarried.
I have her death record from SP as follows:
Janet Sutherland cottager widow of Angus Sutherland (crofter and woolen weaver) died 17 Jan 1900 Achnacraig Berriedale Female aged 87yrs Father: John Sutherland Crofter (dec), Mo: Catherine Sutherland (MS Gunn) (dec) debility from age gradual, no regular medical attendant. Informant - John Sutherland (neighbour - present)
And her parents (John Sutherland and Catherine Gunn) census returns if you would like them.
The 1861 census in Badbea is indeed them, and this is them in 1871 and 1881:
1871 census - Badbea, Berriedale, Caithness
Angus Sutherland Head M 67yrs Woolen weaver b. Dunbeath, Caithness

Angus us by himself and Janet is with her daughter Janet Anderson in Fife.
This is the widowed Janet in 1891:
