Is there a way?

Hello, i'm new here and dont know where to post but here's context for this post, my father had won an ipad mini in robinsons back in 2013 or so and i used my teenage yahoo email at the time and then gave it to my parents back again. My parents gave the ipad to my 4 yo nephew a few months ago and he ended up accidentally having reset it. After trying to recall and trying to log-in, the id got disabled, thing is, i don't remember the i.d so I cant recover it since it being around 7 years ago and I dont have the receipt of purchase it being a prize. Is there a way I can still recover from this activation lock?
