There are also hindu rohilla rajputs in Rohilkhund , even though rohilla is synonymous with pashtun. When i dig deeper, i found out that rajputs of kumoun and rohilkhund, who were under rule of rohillas, served under various chieftains of rohillas. Kumaouni, garhwali and katehr rajputs were martial hindu people so they were recruited by rohillas. They got labelled as rohillas and use surname of rohilla. Same must be the case with sudhans, who were declared "martial race" by british, were heavily recruited and it was not no coincidence that they rebelled in poonch. They have khan surnames. And they are very clear and loud about their sadozai origin, which shouldnt be so surprising for you as sadozais have ruled kashmir for 67 years. Sudhans are too much martial to be brahmins.
No one in Pak claim brahmin ancestry, see exemple of desert friend Mohyal. Sudhans are not pathans and neither they look like one. And hopefully you are joking about to martial to be brahmin thing. In either case they are not Sadozai as much as they want to believe because of little similarity in name.
Also in India there are two types of pathans, nasli pathans and divani pathans to differentiate between real and local converts. No such a thing in sudhans.
May be he is living in city and foriegn country thats why.
I can trace my shajra all the way to marwat and from marwat to lodhi. Our rural folk have very strong sense of roots and cultural identity. Your family lose this sense of identity and roots, when you settle some where else.
You are right, though i may get non-muslim ancestor names now. I wonder how many people can get them?
