Names that are common in the US but not the UK

[ffsfindmeausername]

Just that really, there seems to be certain names that seem very American that you don't tend to hear in the UK such as Chad.
I like the name Chad but no idea why it's not really used in the UK. Can anyone think of any other very "American" names that you don't tend to hear here in the UK or vice versa very British names rarely used in the US?

Do both first names and middle names have to be the same to use Jr etc?

Yes. That is actually the case with my husband and son. They have the same first name, different middle names (both family surnames) and of course the same last name. My son is not a junior and he is called by his middle name.

Yes, he would be III.

Thank you very much @RitaIncognita.

Names like McKinley were the first that came to mind
