I looked up doctor and healer in about 60 different languages and I didn't see anything that was really close to odar.

Baran Bo Odar's grandfather was Tatar who spent some time in China.

Quote:Translated
My father's father was a Tatar, and he was always in the wrong place at the wrong time. First he had to flee Russia before the October Revolution and traveled via China to Germany, where he studied medicine. When Hitler came to power he had to go back to China.

About the language of the Hiungnu and the Tunghu tribes, page 4:

Čuvašisch: odar = shelter for sheep

OK, unfortunately not "doctor"

I found Odar as a last name for family lines in Estonia, Slovenia and Russia, mainly, a couple others here and there in Europe and a couple in Massachusetts in the 1600s but dont know where they were from originally.

(offtopic)
It's obviously Irish, no question at all.
Where's the barn? Baran bo o'daaaar (pointing).

Odar is a word in Mari, meaning "branch" or "sprout". Same in Komi. In Tuvan it is "pasture". In Moksha and Erzya it is "udder". In Macedonian it is "hearse".
