I was looking for my article about finding Sycharth. I knew it was here and, because I'm a lazy git, I did a search for Owain Glyndwr. It wasn't there. I tried again with Owain and there it was!
The problem here is that I searched for Glyndwr, whereas it's properly spelt Glyndŵr. My keyboard doesn't have any W with a hat on it. I'm assuming that many others searching for the same wouldn't bother with the hat over the w either. I don't even know why its there! In Welsh, it would be pronounced the same with a hat or not.
But back to the plot, should I change his name in the title to Glyndwr? It's not the correct spelling, but is more likely to be searched in that way amongst English speaking people.
