is your dad's dad irish or is he english, or is he both?
if your dad's dad is irish you are:
25% german
25% english/british
50% irish

if your dad's dad is english you are:
25% german
50% english/british
25% irish

if your dad's dad is half irish and half english, you are:
25% german
37.5% (that's 3/8) irish
37.5% english

You can't really tell what percentage of anything you are being that just b/c your mom/dad/grandmom/granddad's surname is Irish (or whatever) doesn't necessarily mean that person is full Irish. Does that make sense? Sorry if it doesn't. But none of us can fully trace our backgrounds!

Unless you can work your way all the way back to Adam and Eve, there is no way to ever find out the percentages.

You can NOT go by names...My surname is extant in more than 40 countries, quite a few of them for the past 3 centuries at least.
You Mom's Mom may be English, but HER parents could have come from France (or any other country). Most countries on earth are NOT as old as the U.S. is; Germany did not become Germany until the mid-1800s; look at Africa, even eastern Europe: get an old atlas (or globe) and compare it to a new one. There are so many countries I do not recognize by name because they used to be a different country!
There just is no way to figure it out.
The best deal is to have a comprehensive DNA test and see what it says... Such as from www.familytreedna.com, then you can check the National Geographics Genotype Program to see where your DNA markers flowed through migration.

I wish I could trace my background that far back. Anyhow, I can't tell. You never stated your parents ethnicities, which makes it difficult. I know their surnames.

What percentage of Ulstar are you? Maybe we are related.

Nothingusefullearnedin...is 100%. a) you can't judge ethnicity by name and b) you don't know the "full" ancestry of the people listed

PLUS What about your Dad's dad? and your Mom's dad? You can just ignore them?!

I would find any family history previous to circa 12th century suspect, and a family history back 2000 years as eminently unreliable, at best. The reason - the most reliable data ceases about that time in England. Also, even if you could trace it back, you'd have such a tiny thread of who you actually are "made up" from it would be essentially irrelevant in the scope of your question. If we assume each generation is 20 years, going back even 30 generations (which would be about 1400 AD with our assumption) would mean you'd have over 500 MILLION separate grandparent "slots" that all converged together to make up you today.
