Question:

Will we recognize our relatives in heaven, and is there scripture in the Bible that will tell me this?

Answer:

Yes and yes. In Ezekiel 44: 25 it is discussing the Millennium. That is the time that starts when Christ returns and lasts for 1,000 years until the great throne judgment. We are all in spiritual bodies at that time. There are a group of priests who serve with Jesus Christ during the Millennium and they are called the Zadok (a Hebrew word that means upright ones). They participate in the first resurrection of Revelation 20: 5-6. Back in Ezekiel 44: 25 it states that they can leave the temple (the presence of Christ in other words) and go out into the world in an effort to help an immediate family member who didn't make the first resurrection. How does that tell you that you are going to know your relatives there? Because we're in spiritual bodies at that time and if one of God's elect (Zadok) is able to go and help one of their immediate family members obviously they would have to know them.

Comment:

Don't forget that we are each created in our own image. That means we look now like we looked back in heaven before we came here. When we return to heaven after living in the flesh we will look the same. It is our flesh body that tries to emulate what our spiritual body actually looks like so if you recognize a relative in the flesh how much more when you see them as they really are (and were when you knew them before... after all nobody is really dead, right?).

Doco:

You will find your answer documented here:

Ezekiel 44: 25

25 And they shall come at no dead person to defile themselves: but for father, or for mother, or for son, or for daughter, for brother, or for sister that hath had no husband, they may defile themselves.

Revelation 20: 5-6

5 But the rest of the dead lived not again until the thousand years were finished. This is the first resurrection.

6 Blessed and holy is he that hath part in the first resurrection: on such the second death hath no power, but they shall be priests of God and of Christ, and shall reign with him a thousand years.
