Hi, I'm Gra and pretty much a newbie to Etsy, having starte in late January and made only 8 sales so far, so my experience is, to say the least, very limited.
But I found your question very interesting as tweeking my own titles is pretty much at the top of my to do list. So I went and did a search based on some of your descriptions.
If you type the person's name first your items seem to come considerably higher than typing other parts of the description. So if people want things with quotes from a specific source, it seems you've done the right thing.
On the other hand, I have no means of knowing if most people would look for, say, George Burns or maybe inspirational quote, funny quote, etc.
Anyway, good luck with your shop and hope this at least helps a little bit.
