That stuff looks vaguely familiar.
Just a little bit of clarification on the start of the Jeffersons. The evidence I have is that they formed in 1898, not after 1900 as mentioned in your second article. I am still trying to finalize that evidence. It is interesting to note that if my evidence it true, it would make the Rochester Jeffersons the oldest, continuously operating franchise to become a founding member of the NFL.
If you want to add to your trivia:
Who is the first Western New York team to be a member of the NFL?
Some would say the Buffalo All-Americans, but they would be incorrect. It is the Jeffersons. While Buffalo played enough league games to be included in the standings, they were not officially members until 1921.
