Americans are all about ethnicities like that, such as “I’m half Polish and half German on my mother’s side” or “my family is Italian” though technically they’re from Long Island or Wisconsin or something. Almost nobody describes their heritage as just “American”.
I’ve never heard one say “I’m half English” either.
Personally it just seems a way to label people to let them know they’re not proper Americans.

My father was born in England, I consider myself of half English descent.
