Google your name?

I decided to google my own name today to see if there are any famous Matt Welter's in this world. My own name never came up for anything, but I found a Matt Welter who is poet, pretty damn popular one it sounds. His work is published in major poetry books. Do you think I could say I was him at a poetry reading or something? I mean I do have proof my name is Matt Welter. How would anyone know what he looks like? He's a poet, not an actor.
