Selwyn,
Thank you for checking the book for me. Interesting that there is a photo of a Fraser. Given the page reference, it could be one of the brothers, but I guess we will never know which one. Unfortunately, Le Clerk is a common a name so difficult to find out who he was, but something for me to follow up on. My interest in these two brothers is due to the fact that my Grandmother's eldest brother, Edward Alexander Barber (Ted), married the the Fraser's sister Amy. I know a bit about Ted who was also in the Imperial Yeomanry, but am trying to fill out the details of his life.
Many thanks for your assistance with this query.
