It should be possible to work back, starting with the sasine that was recorded when you bought the house, because normally any sasine will refer to the previous one relating to the same property.
Ideally you would go to the Historical Search Room in General Register House in Edinburgh where you can search the annual calendars for each county. It's not usually necessary to look at the whole of the original document because the listing in the annual calendar will give you all that you need to know.
Generally speaking you can search the sasines between 1780 and the mid-19th century by the name of a property, but this doesn't work so well if it is a house in a street. Also the digitised system can be a little temperamental, and on occasion infuriatingly slow.
Thanks. The search sheets I have refered to the following Sasine from 1818:
James Lawson, Smith, Limekilns, and Elizabeth Taylor, his spouse, seised, in fee & liferent respectively, Feb 18, 1818- In these Tenements of land & Houses with the office houses and yard thereto adjecent being part of the lands of CAIRNEYHILL & PITDINNIES on the north side of the high road leading from Crossford to Torry, extending in whole to 50 falls of ground & Teinds par Carnock; on Disp by Peter Taylor, Minister of the Associate Congreation at Ceres, Aug 21 1817
so question is how do I go back?? who owned it before Lawson?
