And from where are your family origins?

Scandinavians colonized a great many places from England to France to Germany, the Baltic States and Russia. Once settled, they did what everyone else did for hundreds and hundreds of years, and that is marry within their own ethnicity, typically someone from within their village.

It's not unusual for people with English ancestry to have Scandinavian DNA.

That's my point. Since siblings have the same ancestors, they also logically have the same ethnicity. Regardless, DNA frequently reports significant differences in ethnicity because it cannot provide a true picture. I think the estimate is interesting, but IMO it is far too often accepted as gospel. Even that ignores the "noise" that Ancestry readily admits is part of the testing process. Far more attention needs to be given to the ranges included in the report than to the single value that most people rarely look past.

It almost seems that the greater the company's effort is to be precise the crazier the results. I have Finland and Iberia on one test (My Heritage) with no similar results on 23andme. GedMatch results are all over the place depending on the test -- Hungary, Croatia, Papua New Guinea, East Anglia, Orcadian, Kashube. 23andme gives me Balkan (I actually have some Ukrainian ancestry near the Black Sea ) and Scandinavian (no clue). On paper I'm 1/4 Irish, 1/2 German and 1/4 Dutch/Walloon/English/Ukraine.

Still, siblings are not identical. Your older brother could have brown eyes, brown hair and you have blond hair, blue eyes. Is obvious the ethnicity is not identical. Maybe you have more Scandinavian DNA than your brother does. Even if your parents are the same.

I never suggested we were identical in terms of DNA. But siblings descend from the same people, and thus have the same ethnic background. While DNA estimates ethnicity, it in no way defines ethnicity. Researchers have long sought out their ethnic backgrounds, long before DNA testing was available. In today’s battle between DNA companies, ethnicity estimates have become a marketing tool more than anything else.

Let's say you're 2% "Iberian Peninsula" - that doesn't necessarily mean you have a recent ancestor from there. But many of your ancestors from, say, the UK area might compositely have a portion of their DNA from there via the old European migration routes/history. Also, siblings can have quite different percentages, because although you get 50% of your DNA from each parent, you don't get the same 50%, and especially with those small percentages, it is quite possible for one sibling to get enough of it that it shows up while another sibling does not, or has something else that shows up, etc. To further think about this: your mom got 50% of her DNA from each parent. But when you got 50% of your DNA from her, it wasn't necessarily 25% from each of her parents - in theory you could get only DNA from one of her parents and not the other - although this is statistically and practically very close to impossible, it is just to point out that what you get from your ancestors can be anything in a range of percentages.....

do any of them consider the DNA of the American Indian? I was told they don't consider that in the testing. That would be the primary reason for me to get a reading. I'd like to find out if we have any American Indian in us.

They do.
Here is my K13 results from Gedmatch Eurogenes:

West_Asian 2.81
East_Med 9.84
Red_Sea 3.16
South_Asian -
East_Asian -
Siberian 1.84
Amerindian 26.94 <===== I am 26% Native American
Oceanian -
Northeast_African 1.18
Sub-Saharan 9.08

Results from FTDNA:
European 46%
New World 28% <=====28% Native American
Middle Eastern 13%
African 8%
Jewish Diaspora 2%

Results from Ancestry.Com:
Native American 29% <===== I am 29% Native American
Iberian Peninsula 26%
Europe South 17%
Africa North 6%
Scandinavia 5%
Senegal 4%
Europe West 4%

Siblings have the same ancestors, but they do not have the same bits of DNA from those ancestors. One sib may have bits that track to one ethnic group and another have bits that track to a different ethnic group. It's not that the DNA does not provide a true picture. The picture for each sib is different.

Also, genealogy DNA testing does not include the entire genome, only a relatively small part of it. If more bits were tested, sibs might get more similar pictures.

This may be specific to yourself, but I've compared my own DNA uploads from ancestry, DNALand, and GEDmatch and all of them are pretty different.

Interestingly the most significant for my family was that my grandfather's DNA showed no native/indigenous markers with ancestry.com but did on GEDmatch and he was 1.7% NA on DNALand, with no Asian DNA and on ancestry he has about 3-4% Asian DNA. Note, I asked him to test because I am seeking to discover the parentage of his 3rd great grandmother who was descendant of a family with known native American ancestry from Virginia. I figured it would not show up on my results since I am too far removed from this ancestor and I was right. He had much more markers for people who I've met online who are also descendants of families in the community where his 3rd great grandmother was from (Robeson, NC by way of VA) than myself.

Our African regions/nations and their percentages also were pretty different. Mine goes from over 70% with ancestry to less than 65% on DNAland. My grandfather's went down almost 20% on DNALand in particular - we both have, depending on the site, between 25 and 38% European ancestry.
