Lost history from previous year


How do I retrieve my browser history from the prievious year. Two days ago I was looking at an ad from a vender on an old tab I was saving for court case evidence. Then today I find that I cannot bring up my history from 2018 and this retrieval started because the saved tab (and this is on an andriod device by the way) had converted to a current rendition of what the company’s ad currently projects. I need that historic tab to use as proof of deceptive policy. Can you help me get back my history from April 2018?
