To see the births without costing you a ton of credits enter Surname only followed by father/mother it will list all recorded births/baptisms of that couple. If you compare this to Angus children using the Scottish Naming Pattern you might get a feel of who Angus actually belonged to. However, it is not definitive proof only a guide.

That's my thinking.
This is a list of the bairns of Alexander Matheson & Ann Matheson.
These are mostly from the contributed IGI and two from the indexed IGI.
Some of the names are the same as the Canadian ones.
All that proves is that they may have been related.
And I would guess that all Mathesons from Sutherland were related.

I cannot find a marriage for the parents therefore I have no idea if Ann’s maiden name is Matheson.
Best bet is to find a death post 1854 (in Scotland) which should give the name of the mother.
