Any Roxborough's till living on IOM?

Hi there,
I'm heading over to the IOM this weekend and am trying to find traces of my great and great-great grandparents.
My great-great grandfather Roxborough was the Harbourmaster in Douglas (I'm 32 years old so we're talking waaaaay back!) My great grandfather was a merchant seaman....he moved from IOM to Liverpool. They lived in a little house in Peel...I have no idea of the address, it may not even be there anymore.
I was just curious to know if there are any Roxy's still left!

Thanks! :)
