He was the fifth Magistrate of the Pitcairn Islands, holding the office in 1844, 1851, 1864, 1867, 1873–1874, 1880 and 1882. Everyone named Christian on Pitcairn is descended from him; a number of family branches, however, left Pitcairn permanently and settled on Norfolk Island.
He married Mary Young, granddaughter of Ned Young, on 24 March 1839.
