*will we remember our unsaved loves ones in heaven*

I think we will know where they are, but we will have a different view on God's judgments, and will actually praise Him for it. We will see how they chose not to follow Him, and we will love Him so much with our new glorified bodies that we will feel that even the fate of our unsaved ones is totally justified.

When sin is stripped from our souls all together, we will see sin as a disgusting malignant plague. We will not see our loved ones as "we knew them," but rather, we will see them as people who have rejected the love of God and were sentenced fairly.

When someone is infected by zombies, they aren't themselves. They cease to be the person we knew them as. Likewise, in Heaven, we will pray for sinners and things, but we will see them as "infected" with the virus we have been cured of. They aren't the people we knew them as on earth, for we will then see sin and damnation as it really is: a conscious rejection of Jesus Christ and God's mercy that was free all along. We will then praise God for His fairness and mercy and justice.
