Thanks for the contact. As far as we know our Thompsons stayed in Qld, but because of the difficulty we are having in tracing them, anything is possible. The confirmed info we have is my husbands' father, Colin; grandfather, George; ggfather, John.
It would help greatly if at least one had an uncommon christian name! John was married to Jane (Anne) and they went to Warwick in Qld after arriving on the James Fernlie 1856.
They came as husband and wife and with them was Anne/Jane's sister, Sarah. George was born in Warwick along with Sarah, Eliza, Alexander, Mary Anne, Jane and John. These births took place between 1856 and 1869. Don't know if any of this is of interest to you, but that's all I have at the moment.
