The other Jonathan Mayhew is a Dublin artist. You can see a work based on Wittgenstein's aphorism, "The limits of your language are the limits of your world." We share the same name and a taste for Wittgenstein, among other things. He is my facebook friend and he recently asked me about Lorca so I could tell him to google himself and Lorca.
Of course, there is also this one. Most of my google scholar alerts lead back to him.
