Eyraud entered the Holy Ghost Fathers as a novice. Influenced by his brother, a missionary in China, he left Chili for Tahiti in 1862 and arrived at Hanga Roa on 1864 January 2. He was harassed by the islanders, and only stayed nine months before being repatriated to Chile on 1864 October 11. A year and a half later, on 1866 March 27, he settled on the island as a full priest, accompanied by Hippolyte Roussel and three Mangarevan converts.
