riddle - Wikipedia Says So

For this riddle, I used the 'random article' button on Wikipedia until I found something that wasn't too obscure. Can you tell me which page I landed on?

Created by the power of Watts
And named for an argument happily settled,
Although it was not the only resulting settlement.
Joseph was able to make his coat first
In a pile of grateful vegetables.

Hint 1:

I come from where the trail led
And have nowhere else to go.

Hint 2:

Don't die of dysentery
On your way to me.

Hint 3:

I am a place
Though not a state.

Hint 4:

Near me, a place named like a crucible
But not the one where morbid decorations did hang.

Answer

Is the answer...

Amity, Oregon?

Created by the power of Watts

"The town was established between 1848 and 1849 by Joseph and Ahio S. Watt, two brothers..."

And named for an argument happily settled,

"The name "Amity" came from the name of a school that was built by two rival communities after the amicable settlement of a dispute."

Although it was not the only resulting settlement.

There were other settlements that were created in Oregon as a result of the Oregon Trail.

Joseph was able to make his coat first

"Joseph established the first woolen mill in Oregon"

In a pile of grateful vegetables.

Amity is in Yamhill County. Hill = pile and I "Yam" grateful.
