Greetings All!

I am about to bring a novel to the mass market and am working on the cover art. In doing a web search for free artwork I came across a photograph entitled "All About Xavier" and the photographer appears to be Moonglow (it's rather hard to read the very small font even when blown up a bunch). It was located on a genealogy site (of all places...LOL). Anyway, I've fallen in love with this photograph and I want to use it in the cover art. I can't afford to pay very much but I would like to do this properly and pay the photographer something. I can't find them anywhere nor can I find the site again. I've searched everything I can think of, using Google which is what I used before, and for the life of me I can't come across it again. I've also searched by name of the photograph and photographer's handle. Any ideas on how I can find this person?

Thank you,
Lisa
