Edward Steele notes a thing most important regarding my researches, in his journal. He relates the departure in 1858 of George Smith, brother of R.S.Smythe, for Australia. Having recently married in 1857 he was easier to find than I had thought. Married in North Surrey/Wandsworth/Lambeth-ish area with the father's name Edward Smith, and he himself by occupation, a saddler. So far all details correct (father's occupation given as draper). He married a Mary Victoria Crump and sure enough on the shipping list in early 1858 arriving at Melbourne, there he his, the only one of correct age, with a wife, M. V. Smith (daughter of John Sleath Crump). Evidently the plan was for Robert to fund the emigration of the entire family. Eliza and Frederic stayed behind.
There is a small shadow on this revelation; a family on ancestry has already claimed Mary Victoria Crump/Smith as never having left England. We have both made claims upon the same marriage certificate. Having said that I can find no M. V. Smith dying here anywhere, and R.S.Smythe makes no mention of George in his will, nor any offspring of same.
Edward Smith Jnr, George's brother was already potted deep in the soil of South Australia and Robert was in the Riverina, I think, but most definitely in Victoria. I hope George settled here in Victoria, for if he settled in South Australia it's as good as throwing him onto the deck of the Flying Dutchman.
So, George - show yourself!
