All of these come with map refs , you can see the boundary of the homestead and usually a blg or blgs inc a barn etc If you then look up the website or go to google you can normally see the area in sateliite and moving to max magnification if you can click on a road nearby you can find yoursekf in Street scene and then master the camera so you can go up the road looking for amonor road to the homestead and sometimes see part of the original building
Valuation continuation books exist to follow up each online at PRONI and you can then trace the family name changes up to 1922 etc
That can be backed up by the 1901 and 1911 census
