Does anyone know of a guru named Keshav Anand Das?

I believe he has an Ashram in UP and is associated with Prempura Dham Sarkar? I need to know if he is a legitimate guru. He seems to be related to guru Ajay das Ji Maharaj. There has been some suspicious communications with my mother who has sent him money. I need to know if he is a legitimate guru. I have seen videos where he is “curing” women who are sick, but none of it seems real.
