History of Clans in Punjab

Hi there! This is my first Reddit post, so I hope this goes well! For whatever reason, it's been very difficult for me to find any sources about the history of various Sikh clans - in particular, I've been looking for sources about the following clans: * **Kooner** * **Bhullar** * Pattar * Uppal * Sidhu * Dhaliwal * Rai Any help, be that a website or a literature recommendation or something else entirely, would be greatly appreciated. Thank you very much for reading, and, if you decide to help out, thanks so much!
