When you mentioned another Bass serving in Congress at the same time in another state, I immediately assumed it must have been a case of the family dynasty exporting their clan to other states. Instead, it just sounds like the case of powerful political RAT family Richard E. Byrd, Harry F. Byrd & Harry F. Byrd Jr. in Virginia and the unrelated but almost identically named and similarly powerful RAT Senator Robert C. Byrd in West Virginia.
Naah, nobody in rural west-central Tennessee heard of Perkins Bass or the New Hampshire Basses. Just ole Ross.
