On the last "day", which will start with Judgment Day, May 21st, 2011 and end with world annihilation on October 21st, 2011. On May 21st, 2011/Judgment Day, there will be a rapture of true believers coinciding with a mammoth worldwide earthquake that will open all grave and expose their contents. Since the population has exploded recently, most contents will be more then dust powder. Pray now for mercy and salvation.
It is written:
Isaiah 65:17 For, behold, I create new heavens and a new earth: and the former shall not be remembered, nor come into mind.
So no, we will not recognize anyone in heaven.
