This is interesting. Bermuda has 9 medals from the Pan American Games, according to Wikipedia. However, it looks like they failed to count two (!) more medals Bermuda has apparently won in 1991. MJ Tumbridge won an individual silver in eventing and lead Bermudan team to a team silver as well.

Granted, it's possible that confusion was created due to eventing competitions being held in Atlanta instead of Havana, but still, those competitoins still counted, so I guess Bermuda has 11 medals after all.
I'm afraid it's impossible to find complete podiums of those two competitions though.
