A quick and unscientific way to estimate in a perfect scenario, is to divide 100% by 2 (you receive half of each parent's genes) and each successive percentage outcome to represent each successive generation if one ancestor was 100% of which ever ethnicity/race you're looking for.

100% ggggggg grandparent (9)
50% gggggg grandparent (8)
25% ggggg grandparent (7)
12.5% gggg grandparent (6)
6.25% ggg grandparent (5)
3.125 gg grandparent (4)
1.56% great grandparent (3)
0.78% grandparent (2)
0.39% parent (1)
0.195% You

Each ascending relative above you is a generation back. This doesn't account for both parents if both parents had Native American ancestors, in your case. Regardless at .2% in your case, depending on age, you're going back to the mid 1700's to early 1800's most likely.

Okay Thanks well I know I am descended from English settlers in the original 13 colonies so based on that time frame my ancestor was most likely from the Eastern part of the country.I guess one of them had a baby with a Native American.

For sake of simplicity, that could mean you had one full blood ancestor 9 generations ago. That would mean you are a
1/512 th....or .1952%

I got my ancestry results back from 23andMe and it says that I have a 1.2% East Asain & Native American makeup. It broke down into .7% southeast asian, .2% native american and .3% unassigned east asian and native american. So I'm confused. I don't know how much of east asian dna could actually be interpreted as Native American DNA or if it's actually southeast asian DNA. Perplexing and interesting if it's actually true

There is some genetic overlap/linkage among those groups, so that 1.2% is likely all Native American if you have any colonial or central/plains heritage.

There is no way to determine this since ethnicity inheritance is totally random. You do not inherit exactly 50% of an ethnicity from each parent. I should technically be 1/8 or 12.5% Norwegian because I have one great grandparent who was 100% Norwegian but I'm actually only 2% because the inheritance is random. I should also be 25% Italian because I have one grandparent who was 100% Italian but I'm actually more like 31% Italian.

The lower the percentage the more likely the ancestor was that many more generations back. A trace amount of an ethnicity like 0.2% is more like to come from an ancestor around 9+ generations back but it's not exact science and they could have been more like 7 generations back or 12. The only way to really find out is to do the genealogy research.

Yes, Native Americans are essentially of Asian descent.
