A little known resource for information, and one to assist in finding your ancestors between census years, is the Farm Horse Tax. This was a tax that was paid for working horses owned by each farmer.
A second resource to look at for farmers is the Land Ownership Commision records (1872-1873). This records parcels of land greater than one acre.
Both resources can be found at: http://www.scotlandsplaces.gov.uk/ This is a sister site to Scotland'sPeople. But it is free!
TIP: Search by place, not by name!
