Just read through the previous posts, so to clear the mist of time.
There were two Thomas's born to Thomas and Martha nee Hamper,
Thomas b1808 married Mary Ann Pannel, emigrated to New Zealand, then Brisbane, Australia, and settled there.( I am in touch with one of the family). All told they had 12 children.
Thomas John b1811, married Hannah Maria Bryer and had 11 children. They resided in Brighton all their married life and were grocers, school teachers, Thomas John ended his working life as editor of the Brighton Examiner.
The Thomas's had three younger siblings, John, Ann & Sarah but the all died young.
