My wife and I both remember Berestein. Not stain.

And the first time I (we) had a "what?" moment before knowing anything about the mandella effect was Nelson Mandella. I remember we were remodeling our dinning room and had the propaganda box on playing news in the living room and they mentioned Nelson died in prison. This was in the mid/late 90s (96-99). We both remember it because of the house we were doing the work in. Only lived there those 3-4 years. And then hearing he died again 15 years later!? From 2013 on is when we started learning about this convergence of timelines.
