What's Your Name?

What I know: This photograph is from Emma Johnson Ferrer's album, so it's safe to assume these children are Ferrers or Johnsons.  The children appear to be in costumes - perhaps even ballet slippers? It's so androgynous, I'm not even certain that both are boys. Is the child on the left a girl with her hair in a pony tail?  The grass is standing up in places instead of simply lying down as it would if it were placed there. Are they really outdoors and not in a photography studio? And that, folks, is literally all I know about this photograph. Except that it is AWESOME!  Do you know who this is?
