Many lines, some go back to New Amsterdam. More Scot than any other single bunch. Prussian, german, dutch, and english, with one line going back to Africa. On both maternal and paternal, lines going back before the revolution. My wife's background is even more fun. French back to orginal settling of Louisana, with a town bearing their name in Missouri. Her Grandmother was born in Russia, to German parents, volgadeutch, learned to speak german at home, russian outside the home, moved to North Dakota with her parents, Soiux became her third language, and she finally learned to speak English. Married a Sioux, so our children are 1/8 Lakota.
When I first started going to family reunions on my mothers side 50 years ago, the complexion was very pale. Now, the only group not represented at the reunions are Australian Abos. Probably someone a couple of generations down the line will take care of that.
I think the availability of geneology through the net has changed a lot of prejudices. Many surprises in great + grandparents.
