I am not sure what you mean by "I could not make out this name and did not notice him listed artist. ." because how can you check if it's a listed artist, if you can't read the name?
The signature is very clearly M. Mayhew I (senior), and the date is 2012, so possibly a person in the vicinity of the goodwill shop - getting rid of his canvases here - or somebody receiving it as a gift leaving it there. It was framed with another destiny in mind, of course.
