Dear Rajpuana,

Agreed that its of Rajput orgin but the word used by Rajput was सिंह (Sinh) and not सिंघ (Singh), Singh as it is today was used by Sikhs first and later was adopted by other communities.
Present cricket team as far as i know has Yuvraj Singh (Sikh from Punjab), Harbhjan Singh (Sikh from punjab), VRV Singh (Sikh from Punjab) and then you Mahendra Singh Dhoni (Bihari though his father name does not have Singh in it) and RP Singh (from UP) so i do not know what do you mean by this, can ypu pls elaborate.
