Printed engraving from painting, 1853

We have named this gentleman, since the print below it doesn't include his identity.  Dr. Swan Anoa.  (If you're from the Asheville, NC area, you'll know we have a lovely river and town named Swannanoa.)

It only says it was printed by T. Hurlston, in Kilburn, London, England.

It was in a frame which was purchased by a friend at an antique auction.  She wanted to use the frame, so Mr. ? from 1853 was removed.  We are wondering if anyone would pay 75 cents for the print.

We also wonder who he might be.

More credits are:

When checking (superficially I admit) google, I found G. Zobel had also engraved a picture of Queen Victoria, after a painting which is in a museum, but the picture isn't available on line because of copyright apparently.

 No luck in my search for the printers. Jones & Co. 1 Bloomfield Rd., Kilburn, London.

This is to be sold (?) at our Trillium Yard Sale on Saturday, May 3, 2013.
