Hey Bryce,
Was at New Register House today looking up some stuff and while I was looking up a marriage I happened to see on the same page a marriage for a Esther Sutherland (daughter of Neil Sutherland and Janet Bain).....weird hey!!
So it looks like this is a long lost (well only to us) sister to your Angus Sutherland
I copied all the details down for you:
13 July 1877 at Bruan, Latheron marriage between
James Sutherland (crofter & cooper journeyman) widower Fa: Benjamin Sutherland crofter & fisherman dec Mo: Catherine Sutherland (MS Cormack dec) 70yrs Res: Smerly Swiney, Latheron
Esther Sutherland (agricultural labourer - widow) Fa: Neil Sutherland crofter & fisherman dec Mo: Janet Sutherland (MS Bain dec) 50yrs Res: Smerly Swiney, Latheron
Witnesses: John Bain, Margaret Forbes
So this makes her born approx 1827 which would make her a younger sister to Angus by quite a number of years, so my guess is that there are many more siblings!! I checked for her death and got the following:
Death: Esther Sutherland crofter widow 1st William Bain crofter 2nd James Sutherland crofter died 10 Mar 1900 at ??Hill, Smerlie, Lybster aged 75yrs Fa: Neil Sutherland crofter dec, Mo: Janet Sutherland MS Bain dec Heart Disease & Pneumonia. Informant Alexander Bain son & inmate present.
and her census details:

seeing that the 1841 census seems to be you Neil Sutherland (though I cannot actually look at the image and no relationships are mentioned, so have put them in descending age order only) I thought I would look at the other census for this family.
1851 census - Balnabruick, Latheron, Caithness
Neil Sutherland Head 76yrs Crofter of 3 acres b. Latheron, Caithness
Janet Sutherland Wife 50yrs b. Latheron, Caithness

Isabella Sutherland Dau 30yrs Household & Agricultural Labourer b. Latheron, Caithness
William Sutherland Son 19yrs Fisherman b. Latheron, Caithness
Donald Bruce GSon 2yrs b. Latheron, Caithness
Now I realise that Janet (the wife) is too young to have had Angus, so I suspect the old man got married twice, so now all you have to do is check Scotland's People or the New Register House for Neil's death and it 'should' say who his parents were and who he was married to!!!
The IGI shows 2 marriages but they are submitted, so you'll need to check the official certs
Neil Sutherland and Janet Bain 17 Dec 1802 Latheron, Caithness
Neil Sutherland and Janet Campbell 29 Dec 1825 Latheron, Caithness
Are you feeling lucky??
Let me know how it goes, I am eager to know now, good luck
Jenny
P.S E-mailed this to you as well but it came back delayed, so thought I'd put it here as well
