I don't know about the others, but Mary Ann was born 28/11/1828. I said she was 8, but she turned nine on the voyage. To quote Mary Ann:
The Advertiser Monday 14 December 1903 Page 5Mrs. M. A. Vivian, of Mount Pleasant, writes to us as follows:-"I am an old pioneer, having left Blackwall sometime in September, 1837, for Gravesend, where we stayed for three days. We then sailed for this State, touching nowhere till we got to Kangaroo Island, where we dropped anchor for a few days, and then came on to Holdfast Bay, where we landed on December 2, 1837, now 66 years ago. I am the only remaining member of a family of six. My father and mother died years ago, and my brother 16 years since in Melbourne. My two sisters (Mrs. Winch, aged 71, and Mrs. Harrison, aged 75), died in 1901, one on November 1, and the other on November 13. I reached my 75th birthday on November 23 last......I was nine years of age when we landed. We came in the
Navarino...... "
Based on previous research I am reasonably sure that at the time there were two Thomas Wallis's, with families, living in early Adelaide, that bear no relation to each other. I have been here before, most of those same trees intertwine the three separate Hornsby families of Adelaide at the time, who despite living in close proximity, I have established as being unrelated to each other, and indeed are from 3 different English counties.

I do now see a problem... she had one brother and two sisters... maybe my tree is wrong after all
