Who is Hilo Headow?

CEO of Streel and a yazirian, that is the sum total of canon material on him that I'm aware of. But what is his story? At the time of the publication of Zebulon's Guide to the Frontier he still resided at Point True, Pale and had not moved his corporate headquarters to New Streel. So who is Hilo Headow? Question: does anyone else think Headow sounds like a human name?
