Painting by J N Wilson

Some of the research we've been able to find suggest possibly done by James Wilson Morrice. The research had said that when he was affiliated with John Napper he was referred to as J N Wilson. Is this possible? Please help as we have no idea of history or possible artist. Picture is in Excellent condition, needs good cleaning. Frame needs minor repairs. We've just found out that the card on the back is a business card of J.N Wilson. We've added new pics. If anyone knows anyhing about this gentleman we would love to know. We can't seem to find anything and it is a beautiful pic.

Good
