John Smith born London abt 1834
Mr. JOHN SMITH was appointed Secretary of the Marlborough Education Board in the year 1890. He was born in March, 1834, in London, England, and was educated at Marlborough, in Wiltshire, and under his brother-in-law, Dr. Badham. In October, 1855, Mr. Smith arrived in Nelson, and during the ensuing nine years was engaged in surveying, teaching, and farming. In 1864, he was appointed headmaster of the Nelson Boys' School, and eleven years later he accepted an appointment as secretary and inspector to the Westland Education Board.
Can anyone help me to find the family connection between John Smith and his brother-in-law Dr Badham please?
