I am working on an ML algorithm to predict the most likely religion of a person based on the names. For example the algorithm would predict Deepika Patel as a Hindu/Jain, Deepika Kaur as a Sikh, Deepika Geroge as a Christian and Daleela Patel as a Muslim. For training this algorithm, I am looking for specific examples of counter examples. I observed that most of the Hindu names rarely include the alphabets X and Z. But there few counter examples such as Gulzarilal which a Hindu firstname and Zakaria which I know personally is a Brahmin surname. Internet search such as the ones in this link show several Hindu names with the alphabet Z but I am not sure how reliable this information is.
Question: What are some examples of genuine Hindu names that include the alphabets X and Z?
