I am trying to find the death of Thomas Hoskisson. He married Ann Batty in 1820 in Sydney and then seems to have married Mary Williams in Hobart in 1823. there was 3 children born 1 daughter & 2 sons that I can find. However no deaths or marriages for the children and no deaths for Thomas & Mary, I am a decendant of Sarah Pigg & Thomas Upton and am trying to research ALL Sarah children. would be glad to hear from anyone with infromation on Thomas.
