Well, your edits are written at the usual Wikipedia level, so there's that.
You should note that Sacagawea was enslaved by other Indians (in fact, slavery was entrenched in most American Indian cultures, especially in the PacNW). And sold as a slave by Indians to her truly terrible "husband". And that Lewis and Clark praised her to no end and acknowledged that without her, they would have failed.
Also, I don't think it is noteworthy that a former boy's school didn't admit females. There are and were plenty of Catholic "girls" schools that, surprise!, don't admit boys.
