[P-Marlowe]

How many of the founding fathers were foreign born?

All of them were born British Subjects and none of them were born in the United States of America.

They weren’t born in the United States because there was no United States at the time to be born in. They were Original Citizens and as such were eligible under the so-called “Grandfather Clause.” There would be no natural born citizens eligible for close to a generation due to the age requirement.
