I've been rersearching my Sleigh ancestors in the Sottish Borders, and discovered we were Sligh until about 1810. I've managed to get back to a George Sligh, married in Coldstream (Scottish Borders) in 1769. There are loads of Slighs recorded from about the 1690's onward in the Scottish Border area. Our family has no connection with N. America. Does the book you mention on the Slighs give any information on Scottish Slighs? If so, I would appreciate the address where I could get a copy. Very many thanks, James Findlay Sleigh (in Toronto).
