Why does everyone think our information comes from Franklyn?

I am just curious WHY people automatically think that our Indian connection ONLY comes from Franklyn's papers?

Our family never knew anything about his papers. Our story of our Wampanoag ancestors was handed down VERBALLY through many generations.

My Grandmother told me when I was about 10 years old. They never KNEW Franklyn or read his paper.

So I do have Wampanoag ancestors and it has nothing to do with Franklyn.
