the biography of salahudeen ayyub by ibn shaddad i used to have an english translation....very interesting mashallah

then if i remember correctly there is one by shaykh abdullah nasih alwaan who has written a book on the upbringing of children which was abridged by the great scholar shaheed dr habibullah mukhtar shaheed rh who was the son-in law of maulana binori and shaykh ul hadeeth of binori town....

these two come to mind....but im sure the likes of imam dahabi, ibn hajar etc wrote about him....
