There's no reason that there could not be families in Heaven. However, all Christians are part of God's family now, and the bonds that draw human families together probably will not be necessary in Heaven. There, we will all be part of one enormous family, and we will all feel a deep love for everyone else. There will not be the idea that, "I am here with my wife and the two of us are separate from everyone else." We will all be one in Christ.
Your husband or wife or child or parent will be in Heaven with you--if you are a Christian--only if they have been born again by the Spirit of God. If you are saved, your closeness to God will not save the members of your family. They must have their own relationships with Jesus Christ.
We should understand that there will no longer be human procreation in Heaven. The necessity of mating and child nurture will cease. Jesus said of the resurrection, "They neither marry nor are given in marriage, but are like angels in Heaven" (Mark 12:25).
