You won’t find the meaning of Par God anywhere.
Par God means a god who is at par in everything. My family doctor used to tell me that your name is the combination of two Sanskrit words Param & Ishwar. Param + Ishwar = Paresh. According to my doctor, as per my name I am param ishwar. Moreover I am at par (average) in almost everything in life. Coincidentally initials of my name are Par(esh) God(hwani). Thus Par God.
In other words, it is short form of my name Paresh Godhwani.
