BJAbbotts on Family Tree Circles

Hi, My name is Barbara Abbotts (born DAVIS) and Thomas James Wharton b 1860 was my great grandfather. Thomas James Wharton was also known as Wynne (surname). He married Lily Bessie Maria Lathan and they had several children. One of these children was Thirza Emily Eleanor Wharton b 1895 who was my grandmother. Henry Wharton was the brother of Thomas James Wharton AKA Wynne. I seem to have hit a brick wall as I know he emigrated to Queensland, Australia about 15th December 1873. He wrote a letter to his mother on 6th Dec 1875 from Yatale Post, Albert R, Brisbane, Queensland. After that I can find nothing. Any help would me buch appreciated.
Kind Regards,
Barbara
