From the official Charlie Chaplin Facebook page:
"Hitherto unseen photo of Chaplin with George and Emily Seaman on tour in the USA with the Karno troupe, property of Valerie Gough. Valerie is looking for anyone who may have information of George and Emily - her family lost all trace of them after that particular Karno troupe disbanded in 1914. (She thinks they may have had children because there is a little girl in some of the Karno photos, and we know it was not a Palmer child. The Palmers were the only other couple on the tour.) Any leads please let us know - And please circulate."
I agree with my friend, Phil, that the guy on the left is Albert Austin, not George Seaman.
