When I google "Melton painter," I get results for both a C. Melton and a Mike Melton. There may be others on subsequent search result pages. Does your painting show a first name? Does anything indicate when it was painted (20th century, 18th century)?
It may be that you won't find info on the painter if s/he isn't famous. It looks like a nice scene, though, one I'd like to look at again and again.
