DNA TEST help find your relatives?

Recently I used DNA testing to learn about my ancestry, and you might be interested in doing this, too! I did the "Family Finder test", it costs $99. I had good results. The main reason I had the test is I can't locate my great grandfathers ancestors or relatives. His name was Johann Friedrich /Krüger/ John (JOHANN) Friedrich (Fred) Krüger. Below is more info about him.

Anyone can do the Family Finder test, which can connect you with recent relatives and
give you a breakdown of your ancestral origin across all family lines.

In the Family Finder test, you can see what proportion of your DNA comes from which regions of the world.
All it takes
is a painless cheek swab. I had my test done at http://www.familytreedna.com/

Different places of birth for John.
1. On my ggrandfather's naturalization papers he said he was from Prussia.
2. His obituary says he was from Preusen, Germany. Died in Barnesville, Minnesota, USA.
3. My grandmother, Elizabeth Moll/Krueger said he was from Luxemburg. But Luxemburg was not part of Prussia.
4. 1920 census of George Krueger, son of Johann (John) , George said his father was from Luxemburg and his mother from Saxony ( which was true about his mother, Ernestine Wilhelmina Teubner Reichel Kruger).
5. 1920 Census for John Kruger says he was from Prague, but Prague was not part of Prussia.
We have different dates as to when he may have come to this country:
1. 1864 Source is his obituary. age 16
2. June 25th 1867 Source is his first naturalization papers. age 19
3. 1867 Source is the 1910 and 1920 census of MN age 19
4. 1870 Source is the 1900 census. age 22
So 3 records say 1867 is when he came(his first naturalization record, census of 1910 and 1920.
