The largest category is German at a whopping 15%. English only comes in at 8%. Irish is a huge category as well.
(mumbling)...mrf*8^#@...ungrateful Kiwi git!
Just kidding of course..;-)
Just a little pointer....
Many(esp in North America)who claim 'irish' ancestry,by which they think they are of Catholic Irish ancestry,are in fact of Scots or 'Scots-Irish'/'Ulster-Scots' ancestry.
Recent studies have shown that between 50 and 58% of 'irish' Americans are in fact of Protestant faith,and therefore of Ulster-Scots ancestry.
Millions who wave a tricolor every March 17th bedecked in green in fact should be frankly waving a Red Hand Of Ulster flag and wearing orange...
Here's some rambling thoughts I hope will be helpful.
About half of American white folks have German ancestry; in Michigan, the largest ethnic group (of those claiming an ethnic origin for, I think the 1980 census) was German, but it's higher yet, because a number of people of German ancestry stealthily changed to Dutch (or stopped talking about it altogether) in WWI or (sometimes) WWII. There's a town near here which prior to WWI was named Berlin, and the annual fair is still the Berlin Fair; but the people in the town renamed it to Marne, after the river where the German advance was (more or less) stopped.
British Isles ancestry is found throughout the country, however, it possible that it is predominant only in parts of the NE, in parts of the Old South, and in snowbird / retirement destinations (and that, only part of the year).
The truth is there is a lot of British blood in the Irish, and a lot of Irish blood in the British.

They just call us "White" over here.
