Registration notes: Both this entry and 815 are exactly the same tartan (with minor threadcount variations) so why one is called Borthwick and the other Borthwick Hunting is a mystery. This is said to be from a cloth sample in the Tartans Society collection. Thread count differs from the Lord Lyon version (815). Borthwick is an ancient Scottish family of Celtic origin. William de Borthwick built Borthwick Castle in Midlothian in the 14th century. The present chief of the border family is Major John Henry Stuart Borthwick of Crookston, Midlothian. He was recognised by Lord Lyon as the 23rd Lord Borthwick in 1986. Lochcarron swatch. M.O.MacDougal noted that this tartan was made for Borthwick of Crookston in 1951 by Anderson of Galashiels.
