Its origin is Turkish just like it already says, not Russia. It became widely used in Russia because of a famous novel written by Arkady Gaidar called "Timur and His Squad". Gaidar aslo had a son named Timur, so that lead the name to be popular in Russia.
Tumur means iron in Mongolian. I think the English version is Timur. Or Timur is in Ancient Mongolian writing which is little bit different from the modern Mongolian writing. Many Mongolians have this name. Also Tumur is one of my favorite characters in Mongolian novel called "Tungalag Tamir". This name reminds me the character in that novel! Strong, patriotic, trustworthy, and handsome!

Actually Timur was leader of the Mongolians. He was only half Turkic by birth.
