I hate to be this pedantic, but, molly o’scribe, there’s no problem with the prepositionally-terminated clause you’re “correcting.” The sentence is not unclear in that fashion–it still possesses an object to which the preposition “from” refers. Your concern probably stems from the impossibility of ending a sentence with a preposition in Latin, but this is no reason for English writers to follow such a practice, unless they want to be purposefully Romantic.
