Giving a secular name to a muslim

As far as I know, Muslims should have such names that people find them easily identifiable. In some countries - - Muslims are given such a name that people find it difficult to perceive his/her religion. - Sometimes, it becomes hard to recognize their religion because of the language difference. For example, - Turkish names *Tansu Çiller*, *Hulusi Akar*, etc. - American names *Linda Sarsour*, *Sada Cumber*, etc. - Russian names *Mikhail Gutseriev*, *Nail Yakupov*, etc. - Indonesian names *Megawati Sukarnoputri*, *Joko Widodo*, etc. - Pakistani names *Gul Panra*, *Lal Shehjadi*, etc. - Bengali names *Siddharth Sazal*, *Aaruk Munshi*, etc. What does Islam say about that? Please answer according to Quran and/or Hadith. **Note:** direct citation of Hadith and Koran needed.
