Octavia Hamilton's daughter Beatrice Connaught Davis married a Mr. Pinnock and a local Australian woman has noted this on ancestry. She has an account on flickr and I have contacted her. Nothing my come of it but I am nothing if not hope.
A photo of Alice Zavistowski in her married incarnation as Mrs. Marshall Webb has appeared on the net, sans her grand and wild locks but with that restrained and curtly respectable short 1880s haircut and looking a million miles from burlesque. The album holder notes nothing of the Shailers or of the mysterious Aunt Marie Ludlam who came over as part of the ballet company. Lord knows where they ended up - Emmeline's family split into three tragedies with one branch finally hauling it to California where I loose track. Robert Anton Shailer entered the War but no more is known.
