tbh freezing yourself at like 40 and being woke up 300 years later would be pretty awful, all your family and mates would be dead and even if you did manage to track down descendents from your family going up to some familys house, knocking on their door and saying "im your great great great great grandfathers grandson" and throwing photo albums at them of you "300 years ago" would probably result in a one way trip to the psych ward.
