Your having a second passport, one issued by a country other than the US, is not dispositive of your assertion that "Any third generation person born in America to two parents who were born in America [and grandfather was a Euro citizen] is a dual citizen."

Many US citizens born in the US were and children of [both parents] naturalized US citizens. The heritage before the parents becomes irrelevant for citizenship purposes.

So, describe, with particularity, the circumstances that lead to your dual citizenship at birth. One of your parents was not a US citizen, I take it. But if both of your parents were born in the US, under Wong Kim Ark, they are at least citizens, even if not qualified to be president, regardless of the citizenship of their parents.

No.

All the ancestors except my paternal grandfather date back to the 1700's. On one side all the way to the Mayflower.

Both parents born in the US to grandparents who were at the time citizens of the US.

My paternal grandfather, naturalized prior to the birth of my father, was a native citizen of a Euro country which confers citizenship by right of birth on all descendants of native citizens through the third generation.

All I had to do to prove my citizenship was produce my grandfather's birth certificate; my father's birth certificate; and my own birth certificate.

And further, no, there has never been any doubt in my mind that I am a Natural Born Citizen for purposes of Constitutional eligibility to hold the office of President.

What you describe is not dual citizen by birth. It is registration as a Citizen by Descent. Registration as Citizen by Descent is not the same thing as "Any third generation person born in America to two parents who were born in America [and grandfather was a Euro citizen] is a dual citizen."

While you are a natural born citizen of the US, I think your actions demonstrate a lack of resolved allegiance to the US.
