Answer

Rajgarh ke Gāthāpati ke baare mein “moksh gaye” wali jo baat aap pooch rahe hain, uska spasht aur pramāṇik vivaran mujhe Jain paramparā ke sthāpit sroton ke ādhār par nishchit roop se uplabdh nahi hai.

Isliye main is par pakka naam ya kahani batākar anuman nahi laga sakta.

Takeaway

Sorry, I can only provide information that is clearly established within Jain tradition.
