Grosehodge mentioned above (in Reply #17) that Francis Nethersole married Margaret Owen(s). His sister, Frances Ada Nethersole, also married an Owen, Henry James Owen. Was he related to Margaret, or is it coincidence? I understand him to have been a solicitor, of New Inn, London.
I have a very longstanding interest in Howard Staunton, so I would be very interested for any more information about the "consternation" concerning Francis Nethersole's marriage to Margaret.
