What is known about Sai Baba's birthplace and family background based on the introduction to the Shri Sai Satcharita?

The introduction to the Shri Sai Satcharita, as detailed in Chapter 0, states that reliable information regarding where Shri Sai Nath Maharaj originally lived or who his parents were is not available. However, it is certain that he had a significant connection with the Nizam's territory, often referred to as Monglai. He frequently mentioned towns like Selu, Jalna, Pathri, and Aurangabad. An anecdote is shared where Maharaj asked a visitor from Pathri about its prominent residents by name, suggesting a special knowledge of the place, though it cannot be confirmed as his birthplace. The text also notes the uncertainty about whether he was a Brahmin, a Muslim, or even 'unborn' as some devotees believed.
