Hi Scutty
Have only a moment for this and have to run. Back later.
I see in 1901 census as Donald Beaton (60) and Maggie (56) with 2 children Neil (16) and Kate (18). they are at 13 Rhughaisinsh, South Uist. Is this a possibility?
I also see a marriage for Neil Beaton & Mary Mackay, Howmore, South Uist, Sept 11, 1911. Their marriage certificate, available through Scotland's People, will likely give you parental names.
Cheers,
NOTE: Mis-typed the name of the bride. I have corrected it now.
