My brother's DNA ethnicity on the left and mine on the right.

My brother's ethnicity map
Our mother's parents' surnames are Schalin and Lange. Both families considered their nationality to be German. The farthest back we've been able to trace the Schalin family is 1796 to Poland. There is a theory, not proved, that the family was originally Swedish -- Skalin -- and came to Germany in the 1400s. The Langes, we can trace only to about 1860 to the Volhynia region of what is now Ukraine, but at the time it was part of Russia.
Our father's parents' surnames are Muir and Jennings. The Muirs we can trace back to about 1800. Apparently our earliest known ancestor was born in Ireland, but married a Scottish woman and lived his entire adult life in Scotland. The Jennings are from England and came to the U.S. well before the Revolutionary War. They married into several other pre-Revolutionary War families, who came to the colonies from various places in Great Britain.
I really do need to learn more about DNA. I'm amazed our ethnicity results are so different. However, we definitely came from the same set of genes as we have several cousin matches in common. Come to think of it, all these cousin are from our father's ancestors! Wait, I linked my tree to his results. Hmmm… ;)
Confirmed matches in common
I wonder if I can get my other brother to take the spit test.
