Dorcas Hatch (Sprague) Do NOT believe she was a Mayflower Descendant/Richard Warren??

Hello!

The bio for Dorcas notes she was a descendant of Mayflower Passenger Richard Warren, "Mayflower" Passenger

Her Profile pic is also an image frequently used for descendants of Mayflower Passengers.

I cannot find any relationship between Doris and Richard Warren, or any other passenger. Is there something missing?

Dorcas Hatch

Thanks!
