Who would be the artist of a painting cavalier - man in red outfit and has Fred ellery sons name on back portrait?

It's impossible to tell who painted a specific painting without more information. The description you provided is not specific enough to identify the artist. Here's why:

* "Cavalier" is a very broad term. Many artists have painted men in red outfits throughout history.

* "Fred ellery sons" on the back is likely a label or signature. This doesn't tell us who the artist is, only who possibly owned or sold the painting at some point.

To help you identify the artist, you would need more information, such as:

* The painting's style: Is it realistic, impressionistic, abstract, etc.?

* The painting's dimensions: How big is it?

* Any other details: Are there any other figures or objects in the painting? Is there a signature on the front?

* Where did you see the painting: A museum, private collection, online?

With more information, you could potentially research online art databases, auction records, or consult art historians to identify the artist.
