When is The Earliest That Woman Could Get The Right To Vote In The Modern West?

Basically what the title says. And when I say 'Modern West' I mean any time after the French Revolution, in any typically western country.
 
It had proponents (John Adams and Aaron Burr) among the American founders. So it's not impossible to see it happen in the USA near the beginning; although it's very clear that states, not the national government, determine who is a legitimate voter and who is not. Still, if Massachusetts and New York enfranchise women early, other states will follow.

Perhaps have Washington get a different VP - Jefferson? so that Adams is stuck being Governor of Massachusetts. He enfranchises women and it grows from there.
