When I get to heaven will my husband know me? I understand that we won’t be married there as marriage is an earthly union, but will he know who I am?

Yes, there is good biblical reason to believe that your husband will know who you are in the resurrection.

Jesus taught that marriage as we know it now will not continue in the resurrection (Matthew 22:30), but that does not mean our identities or memories of one another are erased. Scripture consistently presents resurrected people as still being themselves.

At the transfiguration, Moses and Elijah were recognizable as distinct individuals (Matthew 17:1–4). After Jesus rose, His disciples eventually recognized Him as the same Jesus they had known before His death (John 20:16, 27; 21:12). Paul also speaks of believers being reunited with one another at Christ’s return (1 Thessalonians 4:16–18), which would have little meaning if personal recognition were lost.

So while your relationship with your husband will no longer be a marriage covenant in the earthly sense, there is no reason to think he will become a stranger to you. You will still know one another, but your relationship will exist in a perfect world without death, jealousy, loneliness, or separation.

That is part of the comfort of the resurrection hope. God does not save anonymous people; He restores real persons, with their identity intact, into a redeemed family.
