My in-laws lived across the street from P.T. Barnum's granddaughter (possibly great-granddaughter - I never really asked) in Florida. A lot of the stuff from the circus was apparently sold off but she still had lots of really cool stuff.

In fact, if I remember correctly, she has a tiny little sofa and end table which belonged to Tom Thumb!
