I have the book "Cheshire Yeomanry". I have reviewed the index and paged through the entire book and cannot find the letters written by any of the Frasers. I have found a photo of Trooper Fraser of the 21st company guarding prisoner Le Clerk commissariat officer to the Boers on page 306, unfortunately I don't know which Fraser this is.Sorry I cannot be more helpful.
