Edward Dobson was born in London, probably in 1816 or 1817. His parents were John Dobson, a merchant, and Elizabeth Barker (1787–1875).
Collet Dobson Collet (1812–1898) was his brother,
Clara Collet (1860–1948) was his niece, and
Sophia Dobson Collet (1822–1894) his sister.
Collet Barker was an uncle, an elder brother of his mother. By the time he started his apprenticeship as an architect and surveyor in 1832, his father had died. He made a sketching tour of the European Continent, his drawings from which were exhibited in the architecture section of the
Royal Academy. While practicing as an architect and surveyor, he attended
University College London to study engineering, and by 1843 he had graduated with certificates of honour in architecture and civil engineering. Edward Dobson married Mary Ann Lough (1821–1913) on 7 May 1839 at
Shoreditch, London, and they were to have ten children. ==Emigration to New Zealand==
