Hamilton and surprising / lolarious actual history

[owlectomy]

I thought that this bit in "Helpless" was just a joke:

[ELIZA]
Laughin’ at my sister, cuz she wants to form a harem

[ANGELICA]
I’m just sayin’, if you really loved me, you would share him

...Until I was idly browsing Angelica Schuyler's Wikipedia page and found that she actually wrote to Eliza, "...if you were as generous as the old Romans, you would lend him to me for a little while."

So I got curious: are there bits of amazing history that you didn't know about before listening to the musical, or things you thought were jokes in the songs that actually happened?
