As a native Hungarian speaker, I've always been fascinated by the history of my native tongue. As we all know, Friar Julianus found Hungarian speaking people in the Ural mountains in the 13th century. However, due to the Mongol invasions, these folks were swept away and brought to Inner-Asia. Even nowadays, there are people in that region with family names called "Mazhar", which is probably a cognate with the Hungarian word "Magyar". My question is that "are there any recordings in the tongue those people spoke whom Friar Julianus met with"?
If such a testimony of ancient Hungarian existed, I think handbooks would be very happy to show it. I'm afraid there's hardly anything older than the years 1600-1700 on most Uralic languages, when European travelers (Witsen) or soldiers (Strahlenberg) began assembling glossaries on Mordvin, Vogul-Mansi, Ostyak-Khanty, etc.
