Activation Lock

I recently have a found a old IPad which no one has used in quite a while in my house. That being said no one remembered the password leading to me having to factory reset it. After factory resetting it, I planned on using the ipad as my own. While setting up the beginning settings I was stopped at the Activation Lock Page asking me for the Icloud and password of the Icloud which was signed in before I had reset it. The problem being that no one remembers the password of the Ipad or the Icloud. Not sure what do to as I've tried to key in the correct icloud but have not been lucky. PLEASE HELP
