I don't think she did remarry. I have often wondered how she survived but if she had land and at least one male employee that we know of may be she did survive alone, as described in that article about pioneer life. I have also wondered if she did remarry would the children, all under 12 years old, take the new father's name. Clearly this did not happen as they are all my Smith ancestors.
However worth investigating now we know her name which i was not able to find out before!! I am so grateful.
My grandfather is james the second son.
Mt father james, Michael smith is his son and was always known to the family as Son. and also Jim Smith of warragul. He worked on the railways.
