Brother,
Thank you for asking this question and it can be a serious pursuit of some believers to find identity in their nationality. What I would encourage you to think about is that in Jesus Christ we are to find our identity and not in ethnic origins, genealogies or some connect with a godly heritage.
Galatians 3:28 New International Version (NIV)
28 There is neither Jew nor Gentile, neither slave nor free, nor is there male and female, for you are all one in Christ Jesus.
The world in the Lord's mind is separated into 3 categories:
1. Jewish people
2. Gentiles (all other greek: ethnos "nations")
3. Church
In Jesus Christ we are all a part of the Church and in Jesus Christ. That is our main identity now and we are therefore in union with all other believers no matter what background, nationality, social status etc.
The only way past racial divisions in America and the lewd history is the peace and forgiveness that the Gospel of Jesus Christ offers. Using scriptures to justify or marginalize any race or people either way is wrong. And unfortunately this has been done both ways.
