Where did the inventor of the ball bearing live?

The brilliant Leonardo da Vinci was first to develop an early model
for ball bearings in the 16th century. Ball bearings, or antifriction
bearings as they are sometimes called, are one type of rolling bearing
that is used to help reduce friction between two moving parts (like
skateboard wheels on an axel).

But it wasn't until 1791 that English inventor Philip Vaughn obtained
the first patent for today's ball bearings while working on carriage
axels.

This one explains that di Vinci sketched a "caged" roller bearing, not
a ball bearing:

ANd this one confirms Philip Vaughn as the inventor (at least first
patent holder) of ball bearings, he lived in England:
