A detailed work on the origins and history of the Circassians in Ottoman language was written by Mehmet Fetgerey Şoenu (1890-1931), a Circassian patriot, who during his short life wrote several works on his ethnic group and on the Caucasus. He was born in to the parents, who escaped the Circassian genocide, a mass slaughtering of this ethnic group by the Russian Empire. He was also one of the leading Ottoman and European wrestles of his time and authored several works on sports.
We could find one institutional example on Worldcat (Michigan State University Libraries).
