A small “inaccuracy” of your own?
In July 1890, the Territory of Wyoming, which allowed women to vote, was admitted as a state. Wyoming became the first state with women suffrage. By 1900, Utah, Colorado, and Idaho joined Wyoming in allowing women to vote.

Sorry about that. I didn’t do any fact checking, just relied on my memory. Thanks for the correction! I just went and did some research. It looks like Wyoming granted women the right to vote a couple of months before Utah.
