In the early 1990's, I was advised that you could get Ordnance Maps of
Ayrshire which showed the Farms, etc.
I did not see the map, but assume they are the along the lines of Army Maps.
If anyone has more detail knowledge about what these maps are called and
where they can be purchased please tell the group.
It may be worth asking the Kilmarnock Council or Dean Castle websites.
As many Boyd families came from villages in Ayrshire, and its many towns,
this short of map may be useful to you in your search. You may need the
current version PLUS ONE MAP nearest to the period that you are researching.
While those website whiz, may also be able to tell us if there is a current
Ordnance map on the Web.
