Forgot to answer your question about Rosanne Barr. To be frank about it NO! And I am glad about that.
However we do have a connection with an even more infamous person.My great-grandfather Scott Barr's first cousin Henry L. Barr married Jesse James daugher Mary Susan James. Many of the James descendents reached formatibal careersin their life times.I know one was a judge. Have a good day Sonia in Oklahoma
