I could give more verses and incidents in which it shows that we will have full memory at least up to and through the judgment but let's skip and go on to after that.
Rev 21:4 And God shall wipe away all tears from their eyes; and there shall be no more death, neither sorrow, nor crying, neither shall there be any more pain: for the former things are passed away.
This verse tells us that we will no longer have any feelings of sorrow or reason to cry or any pain of any sort. I am sure that this indicates that we will not remember those that were lost at the time that is indicated here in this verse.
This was exactly what I was thinking! I have always felt that the Lord will not allow us to remember loved ones who will not be in heaven, because that would be painful and sorrowful, and there will be no pain or sorrow in heaven.
